Fix Help Center site picker - include domain only sites and throw when ZD widget is unavailable

[alshakero]

The Help Center queries /sites to get the user's sites and select a site automatically for the support session, when the user has none, we ask them to enter a site.

The query on trunk didn't include domain only sites, which made us ask the user and cause confusion.

This also throws an error when we try to open the chat widgets and the JS needed is not available. This would make debugging this much easier.
