qtdeclarative: Fix flickable event handling

* With isis2 touch mocking there is a situation where flickable doesn't
  process mouse events even if it has mouse grabbed.
* Patch is cherry-picked from upstream.

+Subject: [PATCH] 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.
