Subject: [PATCH 05/15] libgdm: Unref the manager propagated from task

This instance has already been reffed when passed to the task, and since

we're stealing it with `g_task_propagate_pointer` it won't be unreffed.

We could also do this in the `on_reauthentication_channel_opened` callback

but since the new task will ref it anyway, we can just be clean and do it

here.
