Bug 21084: Fix automatic truncation in authority search

- Makes token splitting work like in biblio search
- Only adds right hand truncation since that's what Zebra also does
- Only adds truncation if the token is not a phrase and ends in a word character
- Adds tests to existing and new QueryBuilder functions

Test plan:

1. Create an authority record for "Duck, Donald"
2. Try contains type authority searches with the following terms and make sure they find the record:
Duck, Donald
donald duck
don duck
"Duck, Donald"
3. Make sure the following search works but does not find anything:
"Duck, Don"
