Crash when moving cursor in Ex Command Menu

[ericluap]

How to reproduce:
Type :e (note the space after the "e")
Press the left arrow key

This leads to oni2 crashing immediately.
By looking at the debug output, it appears it is crashing on this line

oni2/src/Store/VimStoreConnector.re

Line 423 in 13da995

let completions = Vim.CommandLine.getCompletions();

I haven't been able to reproduce this in the latest builds - feel free to re-open if there is still a crash here, though .

I suspect this was fixed either in onivim/libvim@ce177a6 , or possibly onivim/libvim#226
