  -----------
  [Cocoa] SafariViewService does not clear its Now Playing parent application 
when closed
rdar://172257741
https://bugs.webkit.org/show_bug.cgi?id=310570

Reviewed by Andy Estes.

When updating NowPlayingInfo and that info has a sourceApplicationIdentifier, 
we will
tell Now Playing that we are acting on behalf of that application. This gets 
Now Playing
into an inconsistent state after a web view is closed, where it continues to 
believe that
the GPU process is acting on behalf of that application. Clear the state by 
calling
MRMediaRemoteSetParentApplication with a null application when we clear the 
rest of our
now playing state.
