[BUG] Clicking on an input, textarea or select works

Textarea, input, and select element can be scrollable too.
`ZyngaScrollerVerticalRecognizer` will not call `doTouchStart` when they are inside a ScrollView.

To prevent the long press detection to flag the click as a ghost one, we just set the touch duration to 0 in this case.
