Leon Bubova d62130b898 Feature/add unit testing framework and start writing unit tests (acceptance tests) (#708)
* add jest and rewire for testing

* wrap loose code for initMutationObserver() in function and call it instead of just executing it

Otherwise this code is executed everytime state.js is imported somewhere in a file.
This leads to not being able to test properly, since state.js is imported in a lot
of the src files and fails when running the tests since we are missing global environment
settings such as document, window etc in the jest environment.

* export roundDown and getNumberformatter to make them testable as well

* add basic acceptance tests for utils.js, create snapshots and add jest config

* add failing test for buggy behaviour in a separate test case and skip it until fixed

* Fixes after merge conflicts
