Chris Hill-Scott fb33255bd0 Show a more useful message if you get signed out
> Users that allow their session to expire, or access a bookmarked link

The message we were showing before (Please log in to access this page is
the default message from Flask Login).

In order to stop this flash message from appearing, we need to override
the default handler for when a user is unauthorised. We’re overriding it
with the same behaviour, minus the flash message.

If you navigate deliberately to the sign in page it’s unchanged.
