DYN-7790 fix package tour terms of use step

[chubakueno]

Purpose

Dynamo.Wpf.UI.GuidedTour.GuidesValidationMethods.ExecuteTermsOfServiceFlow searches for the TermsOfUse window as owned by DynamoView in GuideUtilities.FindWindowOwned(stepInfo.HostPopupInfo.WindowName, stepInfo.MainWindow as Window) but can't find it due to it being owned by no one (null). This PR thus allows the user to complete the packages tour. Allows for dependent Package Tour testing ticket DYN-7664 to be completed.
