fix(@embark/ens): fix registerSubDomain in tests and add test

registerSubDomain  didn't work in tests because it used the old way
of checking the env, which is checking the `this.env` string, but in
tests, we use the `test` env. So instead, we now check if it is a
known network using the network ID (like we do for other place)
