[CP Staging] Use ref to check if transactions are empty in SearchContext

[JakubKorytko]

Explanation of Change

Removing clearNestedTransactions/setSelectedTransactions from useFocusEffect -> useCallback in MoneyRequestReportTransactionList fixed bug mentioned here but caused this issue.

That is because setSelectedTransactions has searchContextData.selectedTransactionIDs.length in useCallback dependency array in order to skip setting state to empty array when it is already empty. That is fixed using ref to store information whether array is empty already and cleaning setSelectedTransactions dependency array.

That fixes both issues & optimizes SearchContext even more.

• I ran the tests on all platforms & verified they passed on:
  • Android: Native
  • Android: mWeb Chrome
  • iOS: Native
  • iOS: mWeb Safari
  • MacOS: Chrome / Safari

  • A similar style doesn't already exist
  • The style can't be created with an existing StyleUtils function (i.e. StyleUtils.getBackgroundAndBorderStyle(theme.componentBG))
• If the PR modifies code that runs when editing or sending messages, I tested and verified there is no unexpected behavior for all supported markdown - URLs, single line code, code blocks, quotes, headings, bold, strikethrough, and italic.
• If the PR modifies a generic component, I tested and verified that those changes do not break usages of that component in the rest of the App (i.e. if a shared library or component like Avatar is modified, I verified that Avatar is working as expected in all cases)
• If the PR modifies a component related to any of the existing Storybook stories, I tested and verified all stories for that component are still working as expected.
• If the PR modifies a component or page that can be accessed by a direct deeplink, I verified that the code functions as expected when the deeplink is used - from a logged in and logged out account.
• If the PR modifies the UI (e.g. new buttons, new UI components, changing the padding/spacing/sizing, moving components, etc) or modifies the form input styles:
  • I verified that all the inputs inside a form are aligned with each other.
  • I added Design label and/or tagged @Expensify/design so the design team can review the changes.
• If a new page is added, I verified it's using the ScrollView component to make it scrollable when more elements are added to the page.

I notice that when going back from MoneyRequestReportActionList we already reset selectedTransactionIDs to empty array. But I don't understand why the new state isn't applied

Got it

I will copy-paste from our chat for potential future readers:

clearSelectedTransactions was not in dependency array of useFocusEffect -> useCallback in MoneyRequestReportTransactionList, that caused the function to run with old data.

But it was not added because clearSelectedTransactions has setSelectedTransactions in dep array and previously setSelectedTransactions had searchContextData.selectedTransactionIDs.length in dep array.

That caused the following: clearSelectedTransactions updated searchContextData.selectedTransactionIDs.length to 0 and setSelectedTransactions was rebuild -> clearSelectedTransactions was also rebuild

We have a cycle there so the screen above would re-run callback at every call(!)

Thanks to ref setSelectedTransactions dep array is empty while keeping the optimization of not setting empty array when it is empty already
= less re-renders
