Bug 17384 - Categories do not display in patron editing form if they have only one category assigned

To reproduce:
- Go to Home > Administration > Patron categories
- Make sure that you have only one category for a category type.
  Examples: Only one category "Staff" for category type "Staff" or
  Only one category "Library" for category type "Org."
- Edit a patron or create a new patron
- Verify that categories of examples above do not show up in category drop down
- Go back to Home > Administration > Patron categories and add categories to
  both category types
- Edit or create a new patron. Veryfy that categories show up in dropdown.

To test:
- Apply patch
- Make sure you have a category type with only one category assigned
  (e.g. category taype Staff with category Staff)
- Edit a patron or create a new patron. Verify that the category
  shows up in categroy drop down.

- Additional test: Verify that template param 'catcode' from removed line
  is not used in template memberentrygen.tt
