test-stream-tube fails because of a deadlock.

I have initially reported this against glib, but seems it is a tp-glib bug
actually. See https://bugzilla.gnome.org/show_bug.cgi?id=667774.

We should be using async variants for
tp_unix_connection_send_credentials_with_byte() and
tp_unix_connection_receive_credentials_with_byte() and probably get them into
glib (see https://bugzilla.gnome.org/show_bug.cgi?id=629503)
