[480773] Manage better editor opening on Eclipse restart

- Update DDiagramEditorImpl.persistViewerSettings() to test
DiagramEditPart instead of Diagram because on standard editor closing
the Diagram will be always null and settings will never be persisted.
- Regression detected through
RefreshWithCustomizedStyleFromTabbarTests.testChangeLineColorFromTabbar().
