[Pref DataStore] Deadline & Priority switches go in infinite loop

[anidhamal]

Issue :: When both deadline and priority are selected, leaving the app and reopening, makes deadline & priority switches go in infinite loop
Steps to reproduce:

• Launch app from preferences_datastore branch
• Select both deadline and priority option
• exit the app by back pressing
• launch the app again
• deadline and priority switches go in infinite loop

Why::
After reopening,
updateSort -> enableSortByPriority -> SortOrder.BY_PRIORITY -> updateSort -> enableSortByDeadline -> SortOrder.BY_DEADLINE_AND_PRIORITY -> enableSortByPriority -> SortOrder.BY_PRIORITY -> updateSort -> ♾

Solution ::
Inside enableSortByPriority / enableSortByDeadline mtds, check if the argument is enable and SortOrder is BY_DEADLINE_AND_PRIORITY, return from the mtds.
