Add support for components that extend BasePrechat

[AllanOricil]

Is your feature request related to a problem? Please describe.
I have a Pre Chat component that extends the BasePrechat and I can't run it on the Dev Server.

import BasePrechat from 'lightningsnapin/basePrechat';
export default class preChat extends BasePrechat {
...
}

Describe the solution you'd like
Create a way to locally simulate derived Chat components.

Describe alternatives you've considered
I have to deploy the component to Salesforce to test. It is really painful.

is the casing correct?

import BasePrechat from 'lightningsnapin/BasePrechat'; import { api, track } from 'lwc';

@Andries-Neyens no idea. When I tried it did not work. Maybe it is working now.
