blueman: fix fail to enable bluetooth issue

When launch blueman-manager while bluetooth is disable, it may fails
with error:

  Failed to enable bluetooth

Because when get bluetooth status right after change its status, the
status may not be updated that plugin applet/KillSwitch.py sets the
bluetooth status via method of another dbus service which doesn't return
immediately.

Provides a new dbus method for PowerManager which checks whether dbus
method SetBluetoothStatus() has finished. Then it makes sure to get
right bluetooth status.
