Title: [bug] #33287 Contact creator wrong error behavior

http://joomlacode.org/gf/project/joomla/tracker/?action=TrackerItemEdit&tracker_item_id=33287&start=0
To test: enable the contactcreator plugin
When creating a user in frontend "Create new account" or backend and the user name is the same as an already existing Contact alias, the user may be created but the error is picked from com_contact and produces a false error as the user has been created.
