[PATCH 3/8] adapter: add DeviceAdded signal when existing device is added

[Arik Nemtsov <arik@wizery.com>]

Emit a signal when an existing device is added to the device list of the
adapter. These are devices which are added on adapter startup, from
stored link-keys, long-term-keys, etc. These devices will appear in the
"Devices" property of the adapter.
