When using angular.bind as a second parameter of an angular.$q.Promise, the annotation specifies that angular.bind may return null. This CL updates the annotation of the then function of angular.$q.Promise for the second parameter so that it accepts a null value.

Usage:
promise.then(null, angular.bind(this, function(error) {}));
