500 Error on Login for newly created admin user without assigned projects

[awojtczyk]

Bug Description
Newly created admin users encounter a 500 error during login if they do not have any projects assigned. The issue appears to be linked to the HasProjectMiddleware, which fails to handle cases where no projects are associated with the user.

Expected Behavior
Admin users should be able to log in even if they have no projects assigned.

Additional Context
Assigning the 'default' project to the newly created admin user as the first user resolves the issue. Adjusting the HasProjectMiddleware to assign or handle 'default' projects automatically might fix the problem.
