Fix crash when a standard bus isn't available

Commit 1f6fa1f37a added a way of
suspending delivery of messages to standard buses when they connect and
resuming delivery when the main loop starts. As a side-effect, we caused
an attempt to do dispatching even after the connection failed. The D-Bus
library doesn't like that.
