ALE overwrite the python-mode linter Location List

## Information

**VIM version**

```
VIM - Vi IMproved 8.2 (2019 Dec 12, compiled Nov 09 2021 19:35:34)
Included patches: 1-3582
```

Operating System:

Updated arch linux

## What went wrong

Here's my minimal vimrc to reproduce the bug:

```
silent! call plug#begin()
Plug 'dense-analysis/ale'
Plug 'python-mode/python-mode', { 'branch': 'develop' }
call plug#end()

" pymode
let g:pymode_rope = 0 " using YouCompleteMe instead of rope
let g:pymode_lint = 1
let g:pymode_lint_unmodified = 1
au FileType python setlocal wrap
```

After installing the pluggins with vim-plug, ALE refresh the output of `PymodeLint` Location List. Here is the link with [screencast](https://asciinema.org/a/Ri6Sf24KOiAGAKxZMaASikska)

## Reproducing the bug

1. Use the vimrc from above
2. Try to save any python file

I see the `let g:ale_lint_on_save = 1` is set, althoug I'd like to see it autoconfigured based on `g:pymode_lint`

If it's overcomplicated, at lease other persons maybe will find the solution quickly next time.

**upd** On another hand, why ALE at all touch Location List, it it doesn't do anything with it? Isn't it better to not bother itself with touching it?

Start with the minimal vimrc and reproduce the behavior by saving a Python file while python-mode and ALE are enabled; inspect how PymodeLint and ALE each update Vim's Location List. Done means the interaction has a clearly defined, tested outcome, including whether ALE should honor g:pymode_lint or avoid overwriting the existing list.
