Refactor: Comment out unused code in MainScreenTest

This commit comments out unused code within the `waitForLoaded` function in `app/src/androidTest/java/com/warbler/tests/usecases/main/MainScreenTest.kt`.

- The `Thread.sleep` calls and the `toggleAirplaneMode` function call have been commented out.
