[Bug 1763156] [NEW] Bluetooth doesn't reconnect to my headsetup post resume from sleep

[Anmar Oueja]

Public bug reported:

Steps to repro:

* Cold boot the laptop
* Pair it with bluetooth headset
* Listen to music
* Turn off the headset or turn off the bluetooth on the laptop
* Play music, sound comes out of the laptop speakers
* Turn on the headset back on or the bluetooth on the laptop
* Headset reconnects with the laptop and audio plays from the headset

-- all the above is expected --

* Suspend the laptop
* wait a minute or two for the headset to power down
* Resume the laptop
* Turn on the bluetooth headeset
* It doesn't automatically reconnect to the laptop (not expected behaviour)
* Launch Gnome Settings and select Bluetooth and force the headset to connect
* It connects for 2 seconds then disconnects (not expected behaviour)

The only to get the headset to reconnect again is by restarting the
bluetooth.service using systemctl.
