#19222: Undefined index and incorrect behaviour in WP_User::set_role().

 set_role in WP_User assumes that if the count of roles is one, then the
 only role present is at index 0; it seems that this is not always the
 case.

 This is easily fixed by using current($this->roles) instead of
 $this->roles[0]; the behaviour is otherwise the same, but it will work
 without triggering a notice and will correctly short circuit the function
 when the only element is at a non-zero index.

 A patch against the current SVN trunk is attached.
