Ryan Lortie 345688c9e9 GApplication: don't fail if can't get session bus
If we can't get on the session bus, just behave like a normal non-unique
application.

This turns out to be remarkably easy to implement and lets us avoid
adding a 'dummy' backend.

Add a test for this case as well.

Idea from Zachary Dovel.
