Fixes the return URL for the case in which the dropdown content got replaced after a notification update: As the refresh request is done via AJAX, the return URL previously was `/notifications/getnotificationdropdownui` (the `Context.Request.GetCurrentPathWithQueryString()` value of the AJAX action).
We need to pass in the URL of the actual current page as the return URL.
