This patch sets thesaurus as undefined when linking any field except 6XX
This fixes the case where authrotiy records don't have the thesaurus defined
Consequently - this means that Koha does not support multiple thesaurus records
for authorities outside of subjects
i.e. Using the default linker, and having both an LCSH and Sears record for 'Shakespeare,William'
A 100 entry will find two results and the heading won't be linked. Previously we always linked to the LCSH
To test:
1 - Import the attached auths and biblio (from bug 33159 comment 24)
2 - Set system preferences:
RequireChoosingExistingAuthority - don't require
AutoCreateAuthorities - don't generate
CatalogModuleRelink - Do
LinkerKeepStale - Don't
LinkerModule - default
LinkerRelink - do
3 - Edit the imported bib
4 - Save it
5 - Headings are not linked except 600
6 - Apply patch
7 - Restart all
8 - Edit and save record
9 - Headings are successfully linked
