Bug 35510: Non-patron guarantor missing from CollapseFieldsPatronAddForm options

This patch adds a missing option to the CollapseFieldsPatronAddForm
system preference so that the "Non-patron guarantor" section can be
collapsed by default.

To test, apply the patch and go to Administration -> System preferences.

- Search for CollapseFieldsPatronAddForm.
- In the dropdown of options you should see an entry for "Non-patron
  guarantor."
- Click "Select all" and save your changes.
- Go to Patrons -> New patron and choose a patron category which can
  have a guarantor (for example J - Juvenile)
- The patron entry page should load with all sections collapsed,
  including the Non-patron guarantor section.
- Uncheck  all options in the CollapseFieldsPatronAddForm
  preference and return to the patron entry form. All sections should
  now appear.
