Bug#941341: Some info

[Corcodel Marian]

Follow situations  create sink, card bluetooth:

First start pulseaudio and then start bluez service, because bluez5-util 
monitor changes from bluez via dbus.

Start system with bluetooth service stopped and start bluetooth service 
manual because, again pulseaudio is started before .

When restart pulseaudio, loose card bluetooth structure and need to 
stop/start bluetooth service again, in order to emit property changed 
from adapter/device via dbus.
