    functional-tests: Don't rely on just tracker-control -t to kill tests in time
    
    The command `tracker-control -t` simply kill(2) all tracker processes and
    exits. It does not wait/check the processes to terminate. In some test cases
    it happens that the test case tries to launch its own instance of some tracker
    process, but it fails because the old process is still there.
