Migrate to realm_url, vs realm_uri, in registerQueue response

[gnprice]

The server now returns the realm URL from https://zulip.com/api/register-queue in realm_url, as well as in realm_uri, and the latter is now deprecated.

So we should start getting the value from the new name, falling back to the old name. That way in the future the server can eventually stop sending the old name.

(We already use the new name internally within the app's codebase, so this is purely a matter of how it's parsed from the server's response.)

Implementation

See the similar field on notifications for an example of how to handle this.
