Show organisation breadcrumbs

Added a breadcrumb link to a service's organisation to the
withnav_template. This will only show if a service has an organisation
and the current user is also a member of that org, or the current user
is a platform admin user.

Also removed a couple of unused fixtures from the client_request
fixture.
