Jasmine test with timed function and clearinterval

I have trouble getting a jasmine test to run the way I want it to. The test result is Expected spy _cancelInterval to have been called. even though the _clearInterval function is being called.

The test looks as follows:

it('should clear the interval after receiving unknown error', (done) => {
    // simulate backend sending unknown error
    communicationServiceMock['GET'] = () => Observable.throw(new Error('Unknown Error'));
    subjectService = new ProcessQueueService(communicationServiceMock);
    spyOn(subjectService, '_cancelInterval').and.callThrough();
    subjectService.addProcessByStatusUrl('').statusObservable
        .skip(1)
        .subscribe(
            (status) => {
                expect(subjectService._cancelInterval).toHaveBeenCalled();
                done();
            }
        )
    // advance one polling interval and just a little bit
    jasmine.clock().tick(DEFAULT_POLLING_INTERVAL * 2 + 10);
});

Am I doing anything fundamentally wrong? My first approach was to spy on the window.clearInterval which is internally called in the _cancelInterval function, but that threw even more errors.
