Flickable: Fix bug when flicking twice using touches 

When you flick twice in rapid succession, in the same direction,
the expected behavior is for flickable to be moving quite fast in the
direction of the flicks.

But when you flicked using touch events instead of mouse ones,
the second flick caused Flickable to immediately halt. This change fixes it.
