Feature/move to jest (#744)

* Switch to jest

* Fix jslib-angular package name

* Make angular test project

* Split up tests by jslib project

* Remove obsolete node test script

* Use legacy deps with jest-preset-angular

* Move web tests to common

* Remove build from pipeline

This was only being used because we were not using ts runners.
We are now, so build is unnecessary
