ui: don't mark // in input as a command

Prior to this, IsCommand was returning true for inputs starting with two
slashes and thus showing ">"-prompt.

This is a possible confusion (and unwanted behaviour) because the user
might think that they are writing a command but in fact, the message
would be sent verbatim (excluding first slash).
