TypeError if I trigger 'editor:newline-above' in repl by shift-enter

[focusaurus]

Getting a crash in atom core when in a proto repl buffer with shift-enter bound to editor:newline-above. If I disable that key mapping, the repl evaluates the form properly.

1. Install proto-repl atom package
2. Add proto-repl to project.clj
3. Start a lein repl in a docker container exposing port 9999
4. In atom, connect to that remote nrepl (repl output in atom looks like all is well for that "Refresh complete")
5. Type (+ 7 5) below the repl dashed line and hit shift+enter

Atom: 1.30.0 x64 Electron: 2.0.5 OS: Linux Mint Thrown From: Atom Core
