[Impact]
* It is very annoying to see Bluetooth daemon crash after suspending and resuming when playing music through Bluetooth audio output.
* The better user experience should be that Ubuntu will automatically reconnect to the Bluetooth audio output and play music through it.
[Test Case]
* Pairing Bluetooth audio device.
* Playing music through Bluetooth audio output.
* Suspending the system.
* Resuming the system.
[Regression Potential]
* No obvious regression exists.
[Other Info]
* The patch is just to check if the device still exists in devices list before removed from the list. If it exists, do what should do as original steps. If not, do nothing.
bluetoothd crashs after resuming from Suspend to RAM when it plays music through Bluetooth audio output.
