[forms] edited_entity must be set before calling session_key() EntityFieldsForm.__init__ calls FieldsForm.__init__ which in turn calls self.session_key(). self.session_key() uses self.edited_key to compute the correct session key. We thus need edited_entity to be set **before** calling super's __init__. The bug only occured when EntityFieldsForm was selected because of its one_line_rset() selector instead of match_kwargs('entity').
