pulse-server: work around race condition in SET_DEFAULT/MOVE_*

Browse source 
The default metadata update may be delayed for some time after
SET_DEFAULT, since the session manager has to work on it.

MOVE_* commands need to know what the client thinks is the current
default sink, so that they can decide between "move to default" and
"move to specific device".

To avoid race condition here, stash the default value set by the client
and use it in the MOVE_* commands, until the metadata update arrives.
