- Do not disconnect unexpectedly connected devices if bleak supports reusing them
([35](https://github.com/Bluetooth-Devices/bleak-retry-connector/pull/35),
[`be603ce`](https://github.com/Bluetooth-Devices/bleak-retry-connector/commit/be603ce379f6a46ee750e7c3bcbd79d533d2a3ff))
Bleak 0.17 supports connecting to devices that are already connected in BlueZ.
We now detect this and adjust the BLEDevice to point to the already connected device so they do not
have to wait for a connection.
This also fixes a race where the connection times out but the connection is actually made on the bus
but we think it failed because we hit the timeout, so the next attempt will instead sail right
though and be connected.
