Update archive switcher title and back button text to match the functionality

The archive switcher title will now reflect the fact that once you choose that archive,
you will be on your path to accept the share there.
Clicking the Current archive button, it will add the share to the currently selected
archive and redirect the user to the shared workspace of that archive.
