QMimeDatabase: Fix MIME detection issues with magics in MIME hierarchies
Assume two MIME types A and B are registered, both with the same glob pattern, A being parent of B, A with some magic rule, and B with another magic rule. Given a file that matches the glob pattern and the magic rule of A, the resulting MIME type depended on the order of registration of A and B, because it would just check if some glob matching MIME type was also a subclass of the magic matching MIME type. The patch prefers the the MIME type that matches by magic if that matches by glob pattern as well (i.e. A in our example). The "recommended checking order" of the spec does handle that case.
