UI: Add deferred function to update context bar

Browse source 
With the queued connection in d68484e7, the "Deselect" signal for
sources which are being deleted is never fired, as the object is gone by
the time the queued signal is processed. This results in the context bar
not updating.

This commit adds a new UpdateContextBarDeferred function, allowing
queuing of only the context bar update instead of the whole signal
handler.
