Unchecking Group Item in Profile Does Not Remove Contact From Group

If the 'Group(s)' element is included in a Profile - the user can ADD themselves to the group fine. HOWEVER, if the Group(s) field is exposed in User Account (drupal/user/x/edit) - and the user UNCHECKS a Group option - nothing happens. The user's contact record s/b REMOVED from the Group (group_contact status set to REMOVED, subscription_history inserted...). This is a critical bug because folks are exposing this mechanism to allow self-subscribe and un-subscribe by users.

[Anil - ideally you would have tried this out when fixing CRM-665 - seeing that the Group shows up in View and then doesn't when you uncheck the field. Pls try and think about checking out related operations when implementing bug fixes. Thx dgg]
