Metronome.start() is called more than once when starting an animation

[JoelHobson]

It looks like when you use a Tempo object to keep time, it calls start multiple times with the same count for steps 0 and 1.

Here's some code to reproduce - assumes you've got a space defined somewhere.

const tempo = new Tempo(120);
tempo.every(2).start((count) => {
    console.log('on start: ', count);
});
space.add(tempo);
space.play()

I'm expecting the start function to be called once every two beats, but instead, I'm seeing an 'on start: count' message multiple times per beat. The console.log message is just printing out the same value over and over until the count changes.

Hi @JoelHobson - thank you so much for catching this bug.

It's now fixed and you can try it here (uncomment console.log on line 20):

See if that works for you. Thanks again!

That fixed it, thank you!
