Disable tap on scroll "grab"

[mlynch]

Right now if you "grab" a scroll view to stop the inertial scrolling after throwing it, that will trigger a click.

The issue seems to be happening here, where ionic.scroll.isScrolling gets set to false in this callback which triggers on each scroll event but is canceled unless scrolling stops, then it fires 80ms later:

I think we should find a way to fix that in the short term as it's a pretty annoying UX issue. I'll try to think of some alternatives.

Yep! It even throws a console warning.
