Subject: tests: Avoid using real system bus during tests

When a bus address is unset the default value will be used. While the
session bus address is overwritten during tests, this not the case for
system bus.

Use empty invalid addresses as a safer default to avoid accidental
connections to the external buses.

Issue #51.
