Because the redirect after logging in checks the number of services a user has,
this now needs to be mocked.
Right now this means adding `mock_get_login` to any tests that need a login.
This must be one of the first mocks, so that it can be overridden by any use
of `mock_get_services`, for tests that specifically want to rely on a quantity
of mocked services, or their contents.
This is a bit fragile, but there’s already a TODO in the code to make it better
so ¯\_(ツ)_/¯
Because a user can have multiple services, they need a way to navigate between
them. Normally they can use the ▶ Switcher to do this, except when:
- they first sign in
- they are on a page which isn’t associated with a service (eg user profile) in
which case we can’t use the switcher because it won’t know what the ‘current’
service is
So this commit adds a new page with a (fake) list of services.
