[Demexp-dev] Bug in client

[Felix HENRY]

I've started to use demexp client and it's great!
A small bug:
When you add responses to a question you are creating,
if you click on "add response and link" put you didn't
type anything in the response field, this adds an empty
response. You do not notice it if you do not add further
responses, only later when you vote, and it's too late.
Hope it's clear enough.
