Bug 15381: Use Koha::Authority::Types in some other places

There are 3 place where the auth_types table were requested directly
from the script or a subroutine.  These 3 occurrences are easy to
replace with the new module.

Test plan:
1/ Search for authorities and use the "did you mean" feature for
authorities.
Focus on the authtypecode
2/ Edit authority and biblio frameworks.
The "Thesaurus" dropdown list should be correctly populated (UNIMARC
only).
