[PATCH libinput] test: add another hover test

[Peter Hutterer]

Release one touch point at the same time as a fake touch.

I'll squash it in with the other tests before merging but for easier review
it's separate here. This tests for the scenario Hans pointed out with one
touch ending as we switch to hover.
