Crash when triggering autocomplete

[Prior99]

Oni Version: 0.3.6 Neovim Version (Linux only): 0.3.1 Operating System: Arch Linux

Issue:

Editor crashes ("Oh no! ...") when using autocompletion with RLS on a symbol from an external crate.

Expected behavior:

Editor doesn't crash. It's okay if no autocompletions are available, but I might lose my work here.

Actual behavior:

Editor crashes.

Steps to reproduce:

1. Install RLS (rustup component add rls-preview)
2. Configure Oni to work with RLS:

   "language.rust.languageServer.command": "rustup",
   "language.rust.languageServer.arguments": ["run", "nightly", "rls"],
   "language.rust.languageServer.rootFiles": ["Cargo.toml"],
   "language.rust.completionTriggerCharacters": [".", ":"]

3. Write a simple Rust file using an external crate
4. Navigate cursor to symbol of external crate
5. Press .

I put a $5 Bounty on this.

I just checked this on the current master and the issue occurs there, too.
