Favs notifications should take you to the talk

[stephanj]

When you receive a favs notification on your phone, when clicking the notification it now opens the app. But it would be awesome if it could also take you to the related talk.

I've tested this now with two notifications and it works fine for me, tapping on them opens the app and takes me to either the session about to start or to the voting view.

Might be related to the issue #192 : if you have notifications scheduled on your device that are not backed by a favorite session, when opening the app via notification there is nothing to do for this notification as it is not associated to any session anymore.
