Subject: [PATCH] Verify existence of $_GET key

Otherwise when the file without any specified mimetype was accessed the error log was flooded with entries such as "Undefined index: mime", there can be multiple issues found about this in the forum and our bugtracker.

To test this access `/index.php/apps/files/ajax/mimeicon.php` with and without `$_GET['mime']`.

Fixes itself.
