This issue is part of the topic: we should really abolish the need to first create a group when creating a new project.. (eg. https://github.com/g3w-suite/g3w-admin/issues/612)

Motivation

Suggested solution

Make the trash entry a top-level item? (that encompasses everything else? projects, groups, macrogroups, ...)
