[pulseaudio-discuss] [PATCH v3 8/8] stream-restore: skip entries setting action from gnome-control-center

[Hui Wang]

When users select an output device from gnome-control-center UI, the
sink of this output device will be set to the configured_default_sink
and the default_sink, these actions are expected, but after these
actions, the gnome-control-center will call extension_cb() to modify
the entries in the database, let all stream entries to bind the sink
users select, this is not correct since the sink is default_sink now.

This is a temp fix for this issue, after gnome-control-center fixes
this problem, this patch should be reverted.
