Investigate whether `touchesBegan` is being handled correctly in the presence of a GestureRecognizer

We have found that UIGestureRecognizer
was not correctly filtering touchesEnded
events before passing them on to UIViews
it was anchored on (fixed in #305). We now cover the behaviour of touchedMoved
and touchesEnded
in our tests. It would be good to investigate the behaviour of touchesBegan
, as there's a strong suspicion it's not yet being handled correctly.
Possible first steps: compare behaviour with iOS, see how existing TouchHandlingTests
, try writing a failing test for it and finding a fix.
Quick note about this from #305:
From memory, touchesBegan works slightly differently on iOS. If the gesture recogniser fails or doesn't exist then (and only then) will touchesBegan be called.
