Playback should auto-recover on event, net::ERR_NETWORK_CHANGED

[keybrdist]

Problem: Playback stops when net::ERR_NETWORK_CHANGED happens

Expected Result: Playback should retry once NET connectivity is re-established.

Testing: You can test this by switching wifi connection to Wired or switching between multiple wifi connections.

Expected result: the player should catch these events and retry after x seconds until it receives a connection.
