Same Android TV device cannot be controlled by multiple Remote Two devices

[zehnm]

Description

An Android TV device can only be controlled by one Remote Two device. As soon as a new R2 is paired with the device, the pairing of the other R2 becomes invalid:

DEBUG:androidtvremote2:Connection lost. Error: [SSL: SSLV3_ALERT_CERTIFICATE_UNKNOWN] ssl/tls alert certificate unknown (_ssl.c:2580)

How to Reproduce

1. R2.1: pair with Android TV
2. Verify 1 works
3. R2.2: pair with Android TV
4. Verify 2 works
5. As long as R2.1 doesn't reboot (or probably doesn't reconnect to Android TV) it's still working
6. Reboot R2.1
7. --> R2.1 no longer works, see certificate error in the logs
8. R2.2 still works, even after a reboot

Expected behavior

Multiple R2 can control the same Android TV device.

Integration version

0.4.6

Additional context

This might be caused to the hardcoded client_name passed to AndroidTVRemote:

Confirmed: client_name needs to be unique! Tested with a Google Chromecast.
