lifecycle types do not work with Mixins

[GauthierPLM]

Following introduction of lifecycle hooks types in #371 and #386, completion works well for classes extending Vue directly but does not work with Mixins:

import Component, { mixins } from "vue-class-component";
import MyMixin from "@/mixins/myMixin";

@Component()
export default class Index extends mixins(MyMixin) {}

With the above code example (and a valid Mixin), completion does not work in the class for lifecycle hooks such as mounted. The result is the same when imported by vue-property-decorator.

Tested using WebStorm 2019.3.2 preview, vue-class-component 7.2.1.

Can you provide self-contained reproduction as example repo?

[GauthierPLM]

Here is a minimal project where I was able to reproduce the issue (commit).

Completion in index, which extends Vue, works, but it does not work in HelloWorld component, which extends Mixins (or mixins).

Additionally, TypeScript gives me the following error:

This dependency was not found:

* vue-class-component/hooks in ./src/main.ts

Is there anything to add?

Looks like TypeScript problem. If we have private member in the class, the IntelliSense does not work. It is reproducible without any libs. https://www.typescriptlang.org/play/#code/MYGwhgzhAECC0G8BQ1XTAI2NAvNA5PkgL5JKiQwBC0ApgB4AutAdgCYzzJrpa4EB3APYAnANYQipcuCjQAwnSasOcRCjQAHEQEsAbmGbRN-QmR4B6C9BZDG6AK6MhAWmBCAtppC1mbEkA

I'll fix This dependency was not found: problem.

The latest dev version of TypeScript seems already fixed this problem.
