Emmanuele Bassi f090c3ea49 stage: Add more checks on the stage window retrieval
During destruction, the StageWindow implementation associated to a Stage
might be NULL. We need to add more checks for a) the IN_DESTRUCTION flag
being set and b) the StageWindow pointer being NULL. Otherwise, we will
get warnings during the destruction of the Stage.
