Bug 28676: Cache and retrieve match_count when searching a cached heading

We use match_count to determine if a new authority record should be created,
however,
we were not adding this count to the cache, so if a record returned too many
matches on first
lookup, we would create a new record on the second lookup

To test:
1 - Set Linker Module to 'Default'
2 - Enable  AutoCreateAuthorities  and  BiblioAddsAuthorities and 
CatalogModuleRelink and LinkerRelink
3 - Add two copies of a single authority via Z39
4 - Add two headings for that authority to a bib record (e.g. a 610 and 710)
5 - Save the record and note a new authority is generated
6 - Repeat and see another is generated
7 - Apply patch
8 - Restart all the things
9 - Save the record again, no new authority created
