[Angular] auto-generated stories need to be cast to any

Describe the bug I just tried the upcoming Storybook (6.0.0-rc.13) in an Angular project. After initialisation I head to fix all stories because the args access expressions where invalid.

To Reproduce Steps to reproduce the behavior: 0. create an Angular project in strict mode

1. run npx sb@next init
2. run npm run storybook

Expected behavior The standard storybook should be executable without manual type fixes.

Screenshots

Code snippets I had to tweak the stories with any casts:

export const Primary = Template.bind({}) as any;
Primary.args = {
    primary: true,
    label: 'Button',
};

System: Well… that was unexpected:

Environment Info:
(node:88453) UnhandledPromiseRejectionWarning: TypeError: e.filter is not a function

@gaetanmaisse Actually, I am using Angular 10.0.4.

I guess your E2E tests do not apply the strict mode for Angular. If you do not use strict mode (which entails stricter Typescript settings), you get inferences like these:

So, the story objects are inferred as any and, consequently, args can be assigned without problems.

In strict mode (npx -p @angular/cli ng new projectname --strict), however, the types are inferred more precisely:

I just updated the first thread message to reflect this constraint.
