Bug 27737: Tag editor for authority lookup broken in authority editor

This patch changes the markup structure for the authorities
editor so that it better matches that of the basic bibliographic
record editor. This allows the authority-linking JavaScript to
correctly target fields on both pages.

To test, apply the patch and go to Authorities in the staff client.

 - Create or edit an authority record.
 - Switch to tab 5 and if necessary click one of the tag names (e.g.
   "SEE ALSO FROM TRACING--PERSONAL NAME") to expand the subfields.
 - Click the "..." plugin link next to subfield a ("Personal name" in
   this example).
 - In the popup window, search for an authority record.
 - Click "Choose" next to one of the results.
 - The popup window should close and the authority editor should contain
   data from the record you chose, including a value in $9 and $a.
 - Test with various records to confirm that data in other fields is
   copied correctly, for instanct $d, dates associated with a name, $t
   title of a work.
 - Test other JavaScript-driven interactions in the editor:
   - Duplicate repeatable tag
   - Remove repeatable tag
   - Empty tag
   - Reorder sortable tags (e.g. multiple 500 tags)
   - Reorder sortable subfields
   - Duplicate repeatable subfield
   - Remove repeatable subfield
   - Empty repeatable subfield
