----------------------------------------------------------------------

I would expect logging of unexpected instructions, but these instructions 
originated from guacamole-common-js client.

Personally I would give them a null handler if it's intended for them to be 
received but not to have a side-effect.

>             Project: Guacamole
>          Issue Type: Bug
>    Affects Versions: 1.1.0
>         Environment: guacd: staging/1.1.0
> guacamole-common-js: staging/1.1.0
>            Reporter: Richard Lancaster
>            Priority: Minor
>
> When running guacd with DEBUG level logs, the logs are spammed with: 
> {noformat}
> guacd[9]: DEBUG: Handler not found for "nop"
> guacd[9]: DEBUG: Handler not found for ""
> guacd[9]: DEBUG: Handler not found for ""
> guacd[9]: DEBUG: Handler not found for ""
> guacd[9]: DEBUG: Handler not found for ""
> guacd[9]: DEBUG: Handler not found for ""
> guacd[9]: DEBUG: Handler not found for "nop"
> guacd[9]: DEBUG: Handler not found for ""
> guacd[9]: DEBUG: Handler not found for ""
> guacd[9]: DEBUG: Handler not found for ""
> guacd[9]: DEBUG: Handler not found for ""
> guacd[9]: DEBUG: Handler not found for ""
> {noformat}
> I think the empty strings are caused by these instructions: 
> `0.,4.ping,13.1563882935963`.
