Fixed crash when doing a diff of a Flow Graph vs Perforce. #174

The crash occurred inside of the SetContent method called from SFlowDiff::SetCurrentMode. When the Widget is not set to SNullWidget::NullWidget it assumes that the widget exists and attempts to dereference it, but in the former code the Widget was unset (nullptr) causing the crash.
