Bug 23053: Add phrase index to authority Local-Number

To test:
 1 - Define a matching rule for authorities on field 001 index Local-Number
 2 - In koha-conf.xml raise the zebra_loglevels
     <zebra_loglevels>none,fatal,warn,request,info</zebra_loglevels>
 3 - Export some authorities using the tools->export data
 4 - Import those authorities
 5 - Note no matches found
 6 - View the zebra output log, you should see lots of error 114
 7 - Apply patch
 8 - Copy the indexdefs files to the installed versions
 9 - Reapply matchign rules to staged files
10 - Matches should now be found
11 - Logs should not have errors
