KisMimeDatabase should contain suffixes without '*.' prefix
This code should be adapted as well. The problem is that the file
dialogs need *.suffix to filter the files, and return that as the
chosen filter as well. QFileDialog until Qt 5.9 didn't have
a QString QFileDialog::selectedMimeTypeFilter() const method...
If we make 5.9 our minimum version, we can rewrite KoFileDialog to
be logical and consistent.
