Bug 17344 - Can't set guarantor in quick add brief form

This patch updates the guarantor form to work with the quick add form

To test:
1 - Quick add a 'Kid' patron (or other patron type that may have
    guarantor)
2 - Verify form appears as expected
3 - Test that you can add a patron manually or using selector
4 - Test that deletion works as expected
5 - Test 3 and 4 from the full version of the form
6 - Save or cancel and add a new patron using the full form only
7 - Verify that adding/deleting guarantor works with no errors
8 - Sign off
