Fix appearance of easybake errors; more exception improvements

New class EasyBakeException helps distinguish whether or not it should be displayed to the user; Exception class `error_type` attributes are now applied to the class via decorator instead of to the instance via init; Fixed easybake errors looking for the old json response format; Fixed incorrect error bubble when deleting a synonym after the tag has already been deleted
