When extending config the parser preset is not loaded

[byCedric]

Expected Behavior

I tried to extend the new @commitlint/config-conventional and add some "overrides" into that one. What I'd expect is that the new parserPreset is also reused, besides the rules.

Current Behavior

Right now if you extend configs like there, the parser preset remains undefined. This is a dump I got from the @commitlint/load package.

{
  extends: [ '@commitlint/config-conventional' ],
  rules: {
    'header-max-length': [ 2, 'always', 80 ],
    'type-enum': [ 2, 'always', [Array] ]
  },
  parserPreset: undefined
}

Affected packages

• cli
• core
• prompt
• config-angular

It looks like the tests aren't covering the exact use case of the new conventional changelog parser. I'll take a look tonight to see where the test case is behaving differently. For now, I see that in the tests it's receiving a Promise where the real-world use case is receiving a Function (and thus is not picked up by the // Await parser-preset if applicable-code.
