Fix continuation prompt insertion

Browse source 
* Remove the invisible character inserted along with the
  continuation prompt as it is really unneeded.

* Make the inserted space two characters wide. For some
  reason this is needed, otherwise the continuation prompt
  will be one character short when starting up a REPL from
  the byte compiled functions. Curiously when I evaluate
  `jupyter-repl-insert-prompt` in the current Emacs
  session, the prompt looks fine afterwards.
