Bug 24421: Check if subfields are valid using the biblio tag

To test:
 1 - Enable the sysprefs
     AutoCreateAuthorities
     BiblioAddsAuthorities
     CatalogModuleRelink
 2 - Open a record with a subject heading with a subdivision and add a new subfield, or add a new unauthroized heading to a record and save it
    e.g. 650$aChess$xOpenings$vFiction.
 3 - Save the record, note the created authority and that field is linked
 4 - Save the record again and note the authority number changes
 5 - Find and view the authority linked to the record
 6 - The record is for 'Chess', not Chess openings'
 7 - Search authorities for 'Chess' - note duplicated records
 8 - Apply patch, restart all
 9 - Save the record, auth number increases again, we shoudl create the correct record this time
10 - Save again, auth number should not change
11 - Search authorities and confirm the generated authority has the correct subfields
