Drop dependency to rxjs-compat

Because rxjs-tslint-rules detects both version 5 and 6 of rxjs it
complaints about wholesale imports.

After the jwt library is update, remove the rxjs-compat and revert back
the rule.

* Use jasmine-core 2.99.0 onward but not 3.0 (problem with that version)
* Remove _blank attributes
* Replaces undefined by null

A handy tslint feature

chore: updated to ng-packagr 2 (no need to add rxjs)
