Extra flag for sqlfmt causes file to be replaced by a warning

**VIM version**
NVIM v0.4.2
Build type: Release

Operating System: Arch Linux

## What went wrong
Formatting with the sqlfmt fixer causes all text to be replaced with
`unknown shorthand flag: 'w' in -w`

changing sqlfmt.vim from
```
return {
\ 'command': ale#Escape(l:executable)
\ . ' -w'
\ . (empty(l:options) ? '' : ' ' . l:options),
\}
```

to
```
return {
\ 'command': ale#Escape(l:executable)
\ . (empty(l:options) ? '' : ' ' . l:options),
\}
```

fixes the issue

## Reproducing the bug

1. have sqlfmt installed through the [aur package](https://aur.archlinux.org/packages/sqlfmt-bin/) or [binary](https://github.com/mjibson/sqlfmt/releases/tag/v0.4.0)
2. set g:ale_fixers to `{'sql': ['sqlfmt']}`
3. run ALEFix

then file is replaced with error text

It is possible this is a fixer name collision, and this fixer setup is intended for a different sql formatter. But I haven't been able to find that formatter?
