[tracker] Silence libmediaart log messages

    Silence libmediaart log messages
    
    This was removed in commit 2454185dd8a8459c45e4d32e0c3602f14647bbdd, but
    it is actually still needed to hide log messages from libmediaart when
    running `tracker-extract --verbosity=0`.
    
    The mistake of reusing the same variable to store both log handler IDs
    is now fixed.
