Fix flaky enrollment unit assignment test

[dmcavoy]

This test has been flaky since I updated it #34133. I hit it locally and the output was:

==== FAIL["test_Enrolling_user_in_a_course_creates_other_assignment_objects", "Plc::EnrollmentUnitAssignmentTest", 893.7549107875675]

test/testing/setup_all_and_teardown_all.rb:22:in `run'

It looks like the same hash values just in different orders. So i think the fact that all the categories are the same might be the issue here. So instead I check the other fields individually.

no need to sort this second pair of arrays, since the expected value has only one entry.
