    test: Remove pending timeout source after test
    
    If the whole test file takes more than 15 seconds to execute (for
    example, when running it with GC zeal enabled), the "neverRun" timeout
    will fire and throw an exception, thereby failing the test. Remove the
    timeout source after that particular suite finishes.
