On-boarding flow logic

[systemcrash]

When on-boarding the new user and domains, I add the DynamicDNS provider, then the field

I already own a domain

The first hyperlink is add a new one

But this is 'unexpected' since add a new one is to add a provider, not domains. ( I sent a PR to disambiguate this string ).

OK, the user needs to read the text.

But there's nothing intuitive on this page which tells the user how to add/import a domain...

Recommended: change the link, or add another explicit link to click on the provider added below
