Subject: [PATCH 1/3] Fix notification of QDockWidget when it gets undocked

Before the patch the notification was emitted only when the docker
was attached to the panel or changed a position on it.

It looks like the old behavior was documented in a unittest,
so this patch might actually be a "behavior change".
