Typescript's standard fixer does not update the buffer

## Information

**VIM version**

NVIM v0.4.3
Build type: Release

Operating System: macOS 10.15.5
## What went wrong

When saving Typescript files, the `standard` fixer does not apply the fix to the buffer. I can see from ALEInfo that the fixer program exits with code 1. I tried redirecting the error output to a log file and it gave me the following:

```
/Users/aang/Code/letters-to-reps/frontend/node_modules/ignore/index.js:366
throw new Ctor(message)
^

RangeError: path should be a `path.relative()`d string, but got "../../../../../var/folders/q_/gw98zhrj6vz26cwcsx99pgfw0000gn/T/nvimNKuJAm/3/App.tsx"

at done (/Users/aang/Code/letters-to-reps/frontend/node_modules/run-parallel/index.js:22:10)
```

I also tried cowboy coding the ale fixer code and had it write to the file itself, which works, but then the buffer isn't updated with the changes.

## Reproducing the bug

1. Download these files: https://gist.github.com/nathanielks/a18d52a404559c8c1193e3113bfb9578
2. `yarn`
3. `vim App.tsx`
4. `:ALEFix`

## Additional Info

I tried playing with the fixer in `autoload/ale/fixers/standard.vim`:

```
return {
\ 'command': ale#node#Executable(a:buffer, l:executable)
\ . (!empty(l:options) ? ' ' . l:options : '')
\ . ' --fix %s'
\}
```

That will save the fixed code to the file, but not update the buffer. I'm not familiar with writing Ale specifically enough to know how to get the buffer to update 🙈
