$httpBackend.verifyNoOutstandingRequest fails to throw when digest is not triggered

[katemihalikova]

Overview of the Issue
In unit test, I use $httpBackend.verifyNoOutstandingRequest(); to make sure that no request was done. The test also passes when the request is done, because verifyNoOutstandingRequest does not trigger digest (in contrary to flush and verifyNoOutstandingExpectation) which leads to unpropagated Unexpected request error.
There is a comment asking whether calling digest should be added to verifyNoOutstandingRequest as well, but with no response.

Use Case - testing that $http request is not being done
Angular Version - 1.4.8
Reproduce the Error

    it('should not allow submitting invalid form', function() {
        var ctrl = createCtrl();
        ctrl.submit();
        $httpBackend.verifyNoOutstandingRequest();
    });

Sounds like a reasonable change (if nothing else, restores consistency with verfiyNoOustandingExpectations() and flush()). It will be a BC, though - might be a good candidate for v1.6.x.

@katemihalikova, would you like to take a stub at it (and see how much it breaks our testsuite 😃) ?

Will look into it soon 👍
