+Change: Don't fallback to appId in case the route of file action is not defined
+
+When opening a file in a editor or a viewer the path was falling back to an appId.
+This made it impossible to navigate via the file actions into an app which doesn't have duplicate appId in the route.
+We've stopped falling back to this value and in case that the route of the file action is not defined, we use the root path of the app.
