Subject: [PATCH] module-dbus-connection: fix GCancellable leak

`wp_dbus_connection_disable()` creates a new GCancellable
object at the end, which is never freed if the GObject
is then destroyed. To fix this, override `finalize()` and
clear everything there as well.

Direct leak of 64 byte(s) in 1 object(s) allocated from:
