We have a workaround for Weston not sending wl_touch.frame events after
the last wl_touch.up event. It calls Touch::touch_frame to generate a
fake event. The problem, however, is that it used to erroneously do this
on wl_touch.up events even when it was not for the last touch point.
This in turn, lead to extra frame events being inserted in the middle of
a touch sequence, effectively splitting up one touch frame into
multiple. Accumulated touch state would be handled prematurely,
preventing wl_touch.cancel from working correctly for instance.
This tests that we've stopped doing that.
