Small improvements to `lispy-eval`
First of all, thanks for the great package!
I've been using lispy for a long time, but when I recently switch over to doom emacs, I noticed lispy-eval wasn't working as I expected in the overlay mode. It was defaulting to using cider when it should've been using eros (for Common Lisp and emacs lisp). Also, the formatting included extra quotes. This PR fixes these issues.
I haven't checked the changes with clojure yet, but I suspect there's something broken there as well (cider is now insisting on a symbol argument for cider--display-interactive-eval-result).
Ah, someone's already made a PR for the cider part. I expect it will conflict with mine, but I'm happy to resolve the conflicts if #672 gets merged first.
