Anytime a user clicks "sign out" we should be signing them out server side as well. This can be accomplished by setting the Users.current_session_id = null.
I found that the method User.logged_in_elsewhere doesn't need to check if the current_session_id is None. The current_session_ids in the cookie and db (redis or postgres) then the user should be forced to log in again.
Org users, when looking at the page for their org, see:
> Usage
> Team members
When they click into a service it switches to:
> Team members
> Usage
This is jarring. It should stay consistent. I think it that _Usage_ then
_Team members_ is the natural way of ordering the navigation at the
organisation level, so let’s follow that through to the service level.
This does mean that if someone is a member of both an organisation and a
service that the nav will jump (because it’ll switch to the existing,
service-level order of _Team members_ then _Usage_) but it’s going to
jump anyway because you get all the extra navigation items when you’re a
member of a service.
previously it assumed that invalid_pages would always exist, however it
might be `None` if the error isn't on a specific page. Errors on
specific pages include a page not being A4 or content being outside the
boundary. Errors not on specific pages include the file not being a pdf,
or containing too many pages
Cookies using the hostname as a domain will be set
with a prefix of `.` by browsers, it seems to
ensure all subdomains are included in the scope.
When deleting the `seen_cookie_message` cookie we
want to set its domain without a `.` prefix, to
match the domain set by the original code.
Leaving the `domain` attribute out from the cookie
string will ensure the `.` prefix is not set.
make sure everything is using the `nl2br` formatter that properly wraps
it in markdown to keep everything sanitised nicely. Also write a couple
of tests
Rather than hard coding the page titles, let’s just accept anythin
that’s a real template in the guidance folder – will make it easier for
Karl to edit and create pages.
