[6.16.z] Fix Capsule test case for non-admin user

[Satellite-QE]

Cherrypick of PR: #17422

Problem Statement

The test_positive_read_with_non_admin_user fails when run before the Default org/loc is assigned to the Capsule (search won't find it in that case).

tests/foreman/api/test_capsulecontent.py:1983: in test_positive_read_with_non_admin_user
    assert len(res) >= 2, 'Expected at least one internal and one or more external Capsule(s).'
E   AssertionError: Expected at least one internal and one or more external Capsule(s).
E   assert 1 >= 2

Solution

Assign it to defaults before we try to search.
