ale error on processing go function

## Information

**VIM version**

NVIM v0.4.4
Build type: Release
LuaJIT 2.0.5

Operating System: macOS Catalina 10.15.6

## What went wrong

I use ale for golang linter and fixer.
After I upgraded ale to **v3.0.0** or master(78fa93bd55be70c00d0342655bcdfada338e6e79) yesterday.
Something I don't know went wrong. **v2.7.0** works well for me.
Here is the screenshot.

## Reproducing the bug

My ale config in vimrc is
```
" ale {{{
let g:ale_set_quickfix = 1
let g:ale_open_list = 0
let g:ale_linters = {
\ 'python':['pylint'],
\ 'javascript':['eslint'],
\ 'typescript':['eslint', 'tsserver'],
\ 'java':[],
\ 'go': ['gofmt', 'golint', 'go vet']
\ }
let g:ale_fixers = {
\ '*': ['remove_trailing_lines', 'trim_whitespace'],
\ 'python': ['yapf'],
\ 'go': ['gofmt'],
\ 'javascript':['eslint'],
\ 'typescript':['eslint'],
\ }
let g:ale_echo_msg_error_str = 'E'
let g:ale_echo_msg_warning_str = 'W'
let g:ale_echo_msg_format = '[%code%] %s [%severity%]'
let g:ale_lint_on_enter = 1
let g:ale_fix_on_save = 1
let g:ale_completion_enabled = 0
