Bug 22723: Correct syntax error on confess call in Koha/MetadataRecord/Authority.pm

In Koha/MetadataRecord/Authority.pm the call to confess is missing string quotes.

It may generates this error :

Can't locate object method "confess" via package "Empty String at /usr/share/perl5/MARC/File/XML.pm line 448.
" (perhaps you forgot to load "Empty String at /usr/share/perl5/MARC/File/XML.pm line 448.
"?) at /home/koha/src/Koha/MetadataRecord/Authority.pm line 186.

Simply missing double quotes.
Also missing use Carp to call confess.
