The radio buttons to select the type of service - central, etc. -
are only shown if we can't infer the type based on the user's email
/ default organisation. However, the code to render the page in the
error case didn't accommodate this, nor did it show the version of
the page for adding a local government service.
This fixes the bug by DRYing-up the logic to render the pages. I've
not added a test for this for a couple of reasons:
- It's not a critical bug: no one has complained about it and it
doesn't block the user from adding service.
- It's unlikely to reoccur because the bug involved writing _more_
code than was necessary.
- It's not trivial to test this due to the 3 versions of the page
involved - these are tested for the happy path.
