Guard open_with getreadline for picker

[luukvbaal]

Copied the guard already present in prompt_run() which I assume is there for the same reason.

fix luukvbaal/nnn.nvim#25

Edit: Yeah looked through git blame to find the original relevant issue: mcchrish/nnn.vim#39.

This is because we exit the curses mode when we call getreadline(). We can't do that when we are inside a plugin e.g the (n)vim plugins.

Thank you!

Yeah I figured exitcurses() was the issue here. Although the issue was present for picker mode in general (i.e. nnn -p - in terminal), not just inside the plugins. Guess the underlying reason is just the picker mode redirection.
