AppHost.Bundle.Tests: Fix a flaky test (#32563)
The BundleRename test is an inherently concurrent test which needs the app and the test infrastructure to synchronize.
Originally, the app and the test synchronized using a lock file: the app creates the lock file and waits until the lock is deleted.
However, this caused problems because the test may attempt to delete the lock file even before the app has closed it.
Therefore, this change fixes the issue by using different files to trigger the app's wait and resume steps.
