Bug Description

Launch a Unity 8 desktop session, log out, then log into a Unity 7 session. Launch a Mir-on-X shell like MirAL and then try to launch a Mir client like mir_demo_client_egltriangle. The client will refuse to connect.

Unity 8's upstart script always sets MIR_SOCKET to its old value when the session ends. If MIR_SOCKET wasn't set, then the post-stop script will still set MIR_SOCKET, setting it to "". Mir should interpret this as if MIR_SOCKET were unset.
