Commented Unassigned: License Acceptance window does not appear for a dependent package when the dependency is being updated [3418]

Migrated from an internal bug.

1. Open the latest WPT build VWD and create a new C# WAP
2. Open Manage Nuget packages window
3. Click on the update window. We can see that the update for packages jquery, jquery.ui, ScriptManager.jquery, ScriptManager.jquery.ui is available
4. Update Microsoft.ScriptManager.jquery. We get an License Acceptance window. click on 'I agree' to update the package
5. Both Microsoft.ScriptManager.jquery and jquery packages are updated
6. Follow steps 1 -3 for a new project
7. Now update the jquery package first. Both Microsoft.ScriptManager.jquery and jquery packages are updated but the user does not get the License Acceptance window

Expected : The user should be shown the License Acceptance window

Comments: If the update contains new license url, we should show license agreement.
