requireFailure not working with doubletap

[mattmcdev]

When you add requireFailure of doubletap you get a TypeError: "TypeError: Cannot read property 'requireFailure' of null at db.V.requireFailure".

Changing the requireFailure to swipe, pan, etc. all works.

<div id="trigger"
    hm-tap="onHammer"
    hm-doubletap="onHammer"
    hm-recognizer-options='[
        {"type":"singletap", "requireFailure":"doubletap"}
    ]' ></div>

Simillarly, using a recognizeWith of singletap also doesn't work.

This example from hammerjs shows the regular usage of these options: http://codepen.io/jtangelder/pen/pBuIw

I'll take a look later this week. In a bit of a time crunch for some work-related stuff.

Looking at that, there's a chance that the "requireFailure":"doubletap" is actually being applied to the double tap recognizer.

I get the same problem if I remove hm-doubletap from the element.

Still not working using v2.1.10.

Slightly different error: "TypeError: Cannot read property 'requireFailure' of null
at TapRecognizer.Recognizer.requireFailure "

Looking into this now.
