Ruby: client request: getUrl => getAUrlPart

This is a port of the same change in Python from
f8fc583af3

The description of that commit was:

> I think `getUrl` is a bit too misleading, since from the name, I would
> only ever expect ONE result for one request being made.
>
> `getAUrlPart` captures that there could be multiple results, and that
> they might not constitute a whole URl.
>
> Which is the same naming I used when I tried to model this a long time ago
