Subject: [PATCH] A bunch of tiny little fixes for issues I found while setting
 up docusaurus (#312)

* Do not show users related UI if no users have been specified

* Fixed typo in Docusaurus homepage link

* Allow projects without icons

Not every project has an icon, so avoid showing a broken image in that case.

* Do not show project icon in the footer if there's no footer icon
