Avoiding https://github.com/mrmlnc/fast-glob/issues/158

[tmcdos]

This PR contains a:

• [x ] bugfix
• new feature
• code refactor
• test update
• typo fix
• metadata update

Motivation / Use-Case

I often name my project folders using the pattern/scheme of Client name (project name) - first the name of the client and then in braces the name of his/her project.
However, as described in mrmlnc/fast-glob#158 this raises a problem - even if I use globbyOptions: {extension: false, extglob: false} the problem persists. The solution is to properly escape all symbols inside the context which are treated specially by Fast-Glob - but leave them as is in the actual glob pattern(s) in files.
I am not sure whether my implementation is the optimal one but I am open to discussion.

Breaking Changes

This PR is not supposed to break anything - only to handle some edge cases.

Additional Info

I am using the plugin like this (inside vue.config.js)

    config.plugin('stylelintVue')
      .use(require('stylelint-webpack-plugin'),
        [
          {
            context: path.resolve(__dirname, 'src'),
            files: ['**/*.vue', '**/*.css', '**/*.scss'],
            globbyOptions: {extension: false, extglob: false}, // this used to work for "fastGlob" 2.2.7 but no more works with 3.2.2 - it does not find anything if the folder name contains brace(s)
            quiet: false, 
            emitErrors: false  
          }
        ]);
