Title: Update pythonista.fish

Fix a bug that made the ($VIRTUAL_ENV) string print twice in the prompt.
If the VIRTUAL_ENV_DISABLED_PROMPT env var is not set the ($VIRTUAL_ENV) string is automatically prepended to the prompt by the [activate.fish] (https://github.com/pypa/virtualenv/blob/master/virtualenv_embedded/activate.fish) script.
