Remove user ID check

Remove user ID check

When editing a patron, there are three checks made to disable the save button.
The first two to determine if it's a new user or a user that belongs to a
group you do not have permission to edit sound good. But the third check
assumes that the user making the edits are allowed to edit their own record.

To prevent a use case where the user is part of a group that their group does
not have permission to edit, we should not allow them to save changes to their
own record.  This change removes the user ID check.
