Fix qmltest::event tests

- Stationary points are delivered like updated points after
  05dc0a387ae324f2d6f3d7e633a0a49473f6957a
- QQuickItemPrivate::localizedTouchEvent() seems to need to
  detach QEventPoint instances with Released state, to avoid
  losing the localization during delivery
- calling stationary() or release() without position causes
  the event to occur at the middle of the item, not at the
  last-known position as the test was expecting
