Move old tests from routers directory into a new directory and skip them

[dannyprikaz]

Overview

Our tests for the backend have been failing intermittently, and we want to replace them with tests that don't have the same problem. As we write new unit and integration tests for the backend, it would be useful to move all of the existing tests from the routers directory to a new directory designated for old tests. There they can be referenced when writing new tests without any risk of merge conflicts as people work concurrently on new unit tests and integration tests separately. All of these existing tests should also be modified to be skipped.

Action Items

• Move all existing tests from the routers directory into a new directory test/old-tests
• Skip all of these existing tests
