Title: remove error message when just pressing enter

I don't know if this is the absolute best way to handle this behavior, but I often press enter a few times while I'm in a REPL just to put some space between things. The error messages were bugging me a little so I threw this together to remove them when the user presses enter with an empty query in the REPL.
