Description:

Since the bump, trying to use bash-language-server from neovim through
LanguageClient-neovim (https://github.com/autozimu/LanguageClient-neovim)
doesn't work anymore.

For instance, trying to call the `textDocument/definition` method results in

I've tried downgrading to bash-language-server-1.5.6-1 and nodejs-11.15.0-1 and it works with those versions.

Additional info:
* package version(s): bash-language-server-1.5.6-2, nodejs-12.10.0-1

Steps to reproduce:

1. `bash-language-server start`
2. Try calling a LSP method, for instance `textDocument/definition`.

For my personal scenario, the steps to reproduce are:

1. Install neovim.
2. Install https://github.com/autozimu/LanguageClient-neovim.
3. Configure according to
https://github.com/autozimu/LanguageClient-neovim/blob/next/min-vimrc.vim,
adding

let g:LanguageClient_serverCommands = {
\ 'sh': ['/usr/bin/bash-language-server', 'start'],
}

4. Run neovim on a sample file, such as

a() { }
a

5. Place cursor on second `a` and run nvim command `:call LanguageClient#textDocument_definition()`.
