Added blocker -moz- for ::file-selector-button

[ai]

We also need to change tests.

We need a TDD here:

1. Revert fix
2. Find a way to reproduce bug in the tests
3. Add a fix to be sure that it fix the bug

You may need to use another browsers in the test.

let fileSelectorButtoner = autoprefixer({
  overrideBrowserslist: ['Chrome > 25', 'Firefox >= 82']
})

I suggest replacing all prefixes with a -webkit-

class FileSelectorButton extends Selector {
 constructor(name, prefixes, all) {
    super(name, prefixes, all)

    if (this.prefixes) {
      this.prefixes = utils.uniq(
        this.prefixes.map(i => {
          return '-webkit-'
        })
      )
    }
  }

Yeap, let’s try.
