[AIRFLOW-4100] Correctly JSON escape data for tree/graph views (#4921)
It was possible to end up with invalid JS-in-script if you created
certain structures. This fixes it.
`|tojson|safe` is the method recommended by Flask of dealing with this
sort of case: http://flask.pocoo.org/docs/1.0/templating/#standard-filters
The json_ser function is not used anymore (Flask needs an encoder class)
so it and the tests have been removed. The AirflowJsonEncoder behaves
the same on dates, and has extra behaviour too.
> Possible to create invalid JS on dag pages
