Marco Trevisan (Treviño) a2f98c86ff gio/cancellable: Never call toggle notify callback in locked state ...

We had code to avoid that we could call a toggle "up" notification
callback in locked state, but this was not covering the case in which
the cancellable second to last reference was removed in its cancellation
callback.

In fact, in such case we end up going from 2 -> 1 references during the
signal callback call and this leads to calling the toggle notify
callback in locked state.

To prevent this, add an even further reference before calling the
callback (in locked state, but there's no risk that a toggle-up
notification happens now), and drop it once unlocked again.
