Event command sends empty filter

[scsibug]

Running the "event" command like so:

noscl event 2dd9b62dbca442b5dd2fb8243ab7273117f6ba43d4cdcb213007e8e372453c48

Ends up generating a websocket message like:

["REQ","bb641ed6ae82a8"]

My understanding is that a req command must contain at least one filter.
