Auto-generated home pages are still displaying a home page link

[absempere]

This was implemented: AVAnnotate/admin-client#178

However, projects like https://tanyaclement.github.io/gea-spiritual/ are still showing the home page link.

I've asked whether this should be suppressed in the ToC component, as well (ex: https://tanyaclement.github.io/znh-1939/). For now focus on auto-generated pages. The ToC component will be a separate issue if it should also be suppressed.
