EditorManager: Guard against potential crash

Browse Source 
At this point `entry` should not be nullptr, since the editors passed to
closeEditor should be ones that are managed by EditorManager/
DocumentModel. But there could be misusage of the EditorManager API, or
some other corruption of the managed data in DocumentModel, so be
defensive.
