Only run the startup check if the running application is
'org.eclipse.ui.ide.workbench', which runs in a usual Eclipse IDE.
Requiring this specific app-id prevents the start-up check and
consequently a pop-up in test applications launched by PDE or Tycho for
OSGi Junit tests or general console applications (that still have the
'o.e.ui.workbench' plugin installed) on Windows.
