Add back to service link
Add back to service link

When we moved the ‘Switch service’ link out of the nav on non-service
pages it removed any obvious way of getting back to your service on a
page that doesn’t have the service navigation (the non-obvious way is to
click ‘GOV.UK Notify’ in the black bar).

So this commit adds a ‘Back to service’ link which does the same thing
as clicking ‘GOV.UK Notify’ (tries to send you to your last-used
service, sends you to the list of services if it can’t).
