libtracker-extract: Do not leak GMatchInfo objects.

Glib doc:
A GMatchInfo structure, used to get information on the match,
is stored in match_info if not NULL. Note that if match_info
is not NULL then it is created even if the function returns FALSE,
 i.e. you must free it regardless if regular expression actually matched.
