[tracker/sam/index-file-sync: 9/11] functional-tests: Add tracker_test_main()

[Sam Thursfield <sthursfield src gnome org>]

commit 73a9c9ceabcb8bbc34e8b922cc29f68aae430c37
Author: Sam Thursfield <sam afuera me uk>

    functional-tests: Add tracker_test_main()
    
    This wraps unittest.main() but also sets up logging correctly.
    Previously the logging setup happened as a sideeffect of importing
    the 'configuration' module, which was not a good approach.
