Fix NEWT WindowImpl reparent-recreate w/ GLEventListenerState: Bug introduced w/ commit e2506d7663b752f00f0a98f793ebad52e65bd1e3

In case a reparent action takes place w/ recreate,
only preserve the GLEventListenerState if the window is valid and will become visible again (wasVisible).

Also add proper DEBUG log prefix to GLEventListenerState.
