fix(restClient): protocol in connectionOptions

The protocol _must_ end with a colon. This lead to the prefixUrl to
contain a double colon (`::`), also known as Paamayim Nekudotayim.

For the tests with the protocol set to `http:` the other port (8080) is
now exposed in the container in the CI test setup.
