Repeatable jobs failed to end

it('should allow removing a customId repeatable job', function(done){
    var _this = this;
    var date = new Date('2017-02-07 9:24:00');
    this.clock.tick(date.getTime());

    var prev;
    var counter = 0;
    queue.on('completed', function(job){
      _this.clock.tick(nextTick);
      if(prev){
        expect(prev.timestamp).to.be.lt(job.timestamp);
        expect(job.timestamp - prev.timestamp).to.be.gte(2000);
      }
      prev = job;
    });
  });

Even though the test pass, the repeatable job doesn't actually stop/removed. Might have something to do with the repeatJobId being invalid. Check patch below
