[neovim / native LSP] server quit when self cycle

[kiuKisas]

For example:

// Awesome.res

type test = | Foo | Bar

let t = Awesome.Foo

We got this error:

FAILED: Awesome has a self cycle

Legit.

In neovim and native LSP, the server crash and quit.
It happen to me during refactoring code, I expected to see the error, not that the server crash and quit
