Revert "sd-bus: include queried path in GetManagedObjects"

This reverts commit 92d16a53e3. As it turns
out, this is not how ObjectManager is supposed to work. It is just a
special behavior of BlueZ, but no-one else implements it this way.

Revert the patch as discussed on github, and as such revert to the
previous behavior (as described in the spec).
