[test] Run more tests in jsdom

[oliviertassinari]

Work on #1151:

• Fix the autosize warnings for jsdom
• Workaround Add mocks for element scrolling methods jsdom/jsdom#1422 by replacing .scrollTo(x, y) with .scrollLeft and .scrollTop.
• Set more constraints in the CI so we don't introduce unknown regression

We go from 2% of coverage

to 69% of coverage

for tests running in jsdom.

Two issues I didn't spend time on here. I'm breaking them down into two new PRs.

• Setting the license key doesn't work in watch mode: [license] Use a global storage rather than a module singleton #1384

import { LicenseInfo } from '@material-ui/x-grid';

LicenseInfo.setLicenseKey(
  '0f94d8b65161817ca5d7f7af8ac2f042T1JERVI6TVVJLVN0b3J5Ym9vayxFWFBJUlk9MTY1NDg1ODc1MzU1MCxLRVlWRVJTSU9OPTE=',
);

I wouldn't be surprised if this impacts developers in their project too. Not great

• In the main repo, we have a yarn t xxxx script to only run a specific test, really fast. It would be great to bring it here. [test] Add yarn t support #1385

I have rebased on HEAD.

@dtassone Ok, done. Please review. This is solving most of the pain in #1151. Regarding closing #1151, maybe what would be left is to add coverage for it in the documentation, maybe in this section: https://material-ui.com/components/data-grid/virtualization/.
