New:

- Construct the site logo URL to be rooted at ISite instances returned by
``zope.component.hooks.getSite`` and not only rooted at portal root.
This makes it possible to have sub sites with local registries which return
a different logo.

indirectly it can not be an integration test, either avoid the commit or
change the layer into a functional one.
