title: Deep linking/Navigating to tabbed page in prism not working
body: <p>I have a master detail page as the root page for my application. As a detail page for that I have a tabbed page. In the tabbed page I have a content page and a navigation page containing one content page. In the master detail's OnNavigatedTo I'm retrieving some organisation data from the cloud and then I want to navigate to a manage organisation page which is the plain content page in the tabbed page. </p>
  
  <p>Using NavigateAsync and a relative uri to the manage organisation page I find that the Tabbed Page OnNavigatedTo is hit twice and then I get an exception such as (simplified) below. I can also see Binding errors in my output showing that elements on my manage organisation page xaml tried to bind to the tabbed page view model. </p>
  
  <p>I'm not sure if this is an issue with the view model auto wire change in 6.2 or if it's a deep linking issue or if I've done something wrong.</p>
  
  <pre><code>"Sequence contains no elements".

  <p>Using XF 2.3.1.114, Prism.Forms 6.2, I'm not sure if other packages are relevant. If you think so I can include them.</p>
  
  <p>Also interestingly, it works if I try navigate to the content page in the navigation page from the master detail i.e. "TabbedPage/NavigationPage/ContentPage".</p>
  
  <p>Any ideas what the problem might be?</p>
