Fix project manager user to be created in samae project
Tempest dynamic credential creates the project per test class and adds requested role users to
the same project. Project members, project admins, and project readers share the same project,
but the project manager does not share the same project; instead, the project ends up being
created as a separate project.
Fixing the same and also add the unit test.
