Mirror listener retry

[gregscullard]

Problem
The mirror listener doesn't appear to be setup to retry in the event of a loss of communication with the Mirror Node

Solution
If the listener is subscribing, it should handle an error() event and re-subscribe from the consensus timestamp of the last message (+1 nano) it received. This will ensure no notifications are missed.

Alternatives
There are no alternatives that would ensure no loss of data.

If this is related to the appnet example, it actually does restart listeners on the event of communication loss (see AppnetServer methods that start topic listeners) immediately after the error occurs. Listeners are restarted with crash time -10 seconds.

Though probably a better way, is as you described - to use the timestamp of the last message received a restart time.
