Don't warn about relationships when creating a brand new project

[mraible]

Overview of the issue

With 8.4.0, there's a warning about relationships between entities when creating a brand new project with the jhipster command. This seems like a bad developer experience since they haven't created any entities in the project.

Motivation for or Use Case

The default authority relationship shouldn't generate warnings.
