Bug 21080: Fix patron's attributes display when PA_CLASS is used

When a patron attribute class (AV PA_CLASS) is created, the patron's
edit view is broken:
https://screenshots.firefox.com/62uNhoUtH6rPXm9l/pro.kohadev.org

To recreate:
1. Create 1+ authorised values PA_CLASS
2. Create patron's attributes using it
3. Edit a patron

it depends on the order of the fieldset and the ol elements

This is certainly not the best fix but the display does not look broken!
