macOS: Wake up event dispatcher after running modal dialog helpers

The root event loop may have been exited, so we need to ensure the
event dispatcher is woken up so it can evaluate whether it should
continue or not. For most applications this happens automatically
when e.g. the user moves their mouse or press a key, but for tests
this may not be the case, and the test will stall and never exit
its event loop.
