Add ParasSudoWrapper to test-runtime and bring back register_parachain to test-service (#1811)

* Make register/deregister parachain dispatchables

This makes `register_parachain` and `deregister_parachain` of
`Registrar` dispatchables.

Besides that it brings back the functionality of the test node to
register a parachain.

* Fix tests

* PR review comments
