Bug 9395: Problem with callnumber and standard number searches

This problem happens because there isn't a operator "phr" in the values
of callnumber and standard number search. So many results aren't the
corrects ones.

Test plan:

- Apply the patch
- In the dropbox search menu of OPAC main page header, the callnum
  should have only callnum
- In OPAC advanced search the callnumber and standard number options
  shouldn't have "phr"
- In staff client advanced search the callnumber and standard number
  options shouldn't have "phr"
- Change OPACNumbersPreferPhrase and IntranetNumbersPreferPhrase to "use"
- The options listed before should use now the operator "phr"
- This will resolve the problems with the searches of callnumbers and
  standard numbers in OPAC and staff client (spaces problems, no
  results, inconsistent results, etc...)

I don't know how to reproduce the searching problems described in the
bug, but I can confirm that the patch works correctly to enable/disable
the use of 'phr' in the searches described in the test plan.

System preferences work as described, switching indexes in
OPAC and staff.
All tests and QA script pass.
