QtDBus has allowed this because the bus would stop the message and
return it to us as an UnknownMethod. But it makes no sense to send it,
so let's block it early.
For practical purposes, this allows the tst_qdbusmarshall test to
continue working regardless of which daemon is running the bus. The
message it was checking against only came from dbus-daemon; for users of
systems now running dbus-broker (like my openSUSE Tumbleweed) the
message was different and the test was failing.
