Jest-preset-angular: Support Jest 22

[thymikee]

I guess we can get rid of custom Test Environment, because Jest is now using new JSDOM.
We'll also need to wait for ts-jest to update their coverage-related code (because there was a breaking change in how we pass sourcemaps to transformers).

Let's wait until ts-jest update finishes. It will make jest 22 more stable too in the meantime
