(bug) Session delete isnt working/crashes even when there is no attendance/assessment (child record)

[CritiqalPete]

v 3.02
to reproduce

1. Select a test team (Guadalupe Juniors)
2. Select a session date
3. Choose Delete Session
4. Observe
5. Verify there are no attendances or assessments for that session
   Result: The operation is blocked even where none of the students are marked 'attending'

Note This may require investigating cases where attendance records have been generated with 'attended'=FALSE values being counted as attendance records and blocking delete. What do we do?

ADDITIONAL EXAMPLES

• Bryant Select 2022-2023 (fails to delete through there are not attendance records set)
• switch to the headcount team Cleveland Recess 2022-2023
  Crashes before loading that team

this is an API issue. It is incorrectly identifying the session as "active"
