+Subject: [PATCH] foldermodel: lift screen add/remove handling out of
+ screenmapper
+
+screenmapper is the wrong place for it because we don't know the url
+inside the mapper. Instead handle events in the foldermodel and
+correctly delegate the add/remove actions to the mapper with both our
+screenId AND the activityId
+
+notably the previous code would incorrectly invoke addScreen with empty
+activityIds triggering fallback handling that resulted in incorrect
+m_screensPerPath management (there would be no screen associated with
+our url anymore after a screenAdded signal because our screen got
+associated with no url) and consequently firstAvailableScreen would
+return no screen for our url (remember: we are associated with no url)
+making FolderModel::filterAcceptsRow return false and filtering
+completely valid entries
+
+BUG: 467951
+
+possibly also is the root cause behind
+CCBUG: 467092
