QMimeDatabase: fix regression in alias resolving

The refactoring to support multiple providers broke alias resolving
(e.g. "text/directory" would be an invalid mimetype, instead of being
resolved to "text/vcard"). The unittest didn't catch it because most of
it was running with a single mime directory (and therefore a single provider,
in the new model). Fixed by re-running a number of test methods once we
have a second mime directory.
