Suppress expected RuntimeException in AbstractMediaTest using TestLogger (#4256)

This change addresses an issue where `AbstractMediaTest.testConcurrentPauseAsyncError` prints a `java.lang.RuntimeException: Fail` stack trace to stderr during execution, creating noise in CI logs. This exception is expected as part of the test logic but was not being intercepted.

We now use `TestLogger.install()` to capture the exception, verify it matches the expected "Fail" message, and then clear it, preventing it from being printed to the console. This ensures cleaner test output while maintaining the integrity of the error handling test case.
