tdf#129096: Document Recovery: Use TypeDetection on load
Loading of recovered document happend before via XFilter::filter
is not updating media descriptor of document. But this is
important for password protected documents to store entered password
and used encryption type.
To avoid this problem let's use TypeDetection which during its work
will ask user for password and store all the info in modified media
descriptor before actual recovery attempt.
