* naughty.legacy: Fix a regression caused by a prior fix.
The title was only set "later" because it was called too early.
The intended result was to prevent the code from being executed when
there is no leagcy popup, but it had this side effect.
* naughty.dbus: Expose the new "private" methods so they can be tested.
Because it now uses Gio instead of capi.dbus, it isn't possible to
just shim the backend anymore.
* shims: Upgrade the dbus shims to also emulate some Gio behavior.
As usual, it is the most basic version that produces the correct
result. It doesn't try to comply to the real API.
