Fix/Feat: Error handling and disconnecting flow

[davidrapan]

fix: Task exception was never retrieved

• Not really sure if there is better way how to mimic "from" without raising the Exception...

fix: Catch TimeoutError without logging exception

feat: Improved disconnecting flow

feat: Added serial tag to some debug messages

Hi @davidrapan,

These LGTM. Would you mind making the corresponding changes on the sync version of the library (where appropriate)?

Cheers, Jon

Hi @githubDante and @jmccrohan,

Sure thing! I extended those debug messages also in the sync version. Added that Host unreachable catch in _send_receive_v5_frame. And disconnecting flow already had appropriate error handling.

Have fun!

Merged. Thanks @davidrapan!
