Replace test with one-off

It’s a confusing proposition to have two features which are almost
identical. Even differentiating between them in the template menu would
be tricky.

I think the better thing to do is rename the whole feature to ‘send
one-off message’.

Then if someone wants to use there own phone number or email address,
give them a quick shortcut to doing that, once they’re in the flow.
In the background this reuses the ‘send yourself a test’ code, but
the user is never aware that they’re going through a different route
to send an individual message. So the proposition stays nice and clean.
