tdf#112931 always signal AllUserEventsProcessed
If the last user event triggers a nested event loop, there is
no event in the nested loop, but AllUserEventsProcessed will
not be signaled, resulting in a busy loop in the gtk backend.
So just always signal AllUserEventsProcessed, if it was not
yet signaled.
While at it catch and std::abort on uncaught exceptions and fix
the default to have been signaled, so we won't signal on an
empty list on first run.
