Don't send empty logs

[NiallEgan]

This PR means that if the logs are the empty string or None, we no longer emit them on the socket. This stops extra empty lines being printed on the front end.

We should print an empty string if that's what an avatar's code does right? Maybe we should ask James

Printing an empty string is the same thing as printing nothing at all. If the user did say print(''), this wouldn't print `` but \n - we'd still print that.

Yeah, I would say that's the expected behaviour right? It's what happens if we run python in the terminal
