touch: more fixes in the message pump.
Remove the signal handler when the message-pump terminates. This wouldn't
normally be necessary, but it can happen that the message-pump is terminated,
and then additional GTK+ operations happen (e.g. in unit_tests).
Also check for non-null dispatcher before dispatching events. This can happen
for the first-run dialog, and also in the unit_tests.
