Make sure pressPosition and scenePressPosition are correctly initialized

The problem was that QQuickMultiPointHandler::m_currentPoints were only
initialized when the candidate points matched the min and max number of
points.

So if we wanted to do a two-finger pinch it would only initialize them
when *both* fingers were pressed. Due to the checking of point->state() in
QQuickHandlerPoint::reset(const QQuickEventPoint *point) it meant that it
would only initialize the press position correctly for the *last* pressed
point. This was because the first pressed point would at the point when
reset() was called have a point->state() == QQuickEventPoint::Updated, so
it would not initialize the pressPosition nor the scenePressPosition.

Luckilly we can get the scenePressPosition from the QQuickEventPoint, but
the pressPosition we have to explicitly localize.
