Title: [PDI-8262] Failed to execute runnable (org.eclipse.swt.SWTException: Widget is disposed): further steps - Pentaho BI Platform Tracking

+ Applied fix done in InsertUpdateDialog to dialogs having the same code and thus affected by the same issue.
Unit test is not created as the issue is UI- and threading- related, thus not so easily testable IMO.
