floss: Fix race between adapter prop change and device prop change

AdapterBondedDevices event would insert the remote device addresses
into the bonded list. This event usually comes first and the device prop
change event would update the list afterwards. However, it's found that
they could come in the reversed order and Floss would "miss" the updated
device prop.
