[backend] Fix orga sharing tests (#4538)

[marieflorescontact]

Proposed changes

• Use adminQuery() instead of queryAsAdminWithSuccess as it uses queryAsAdmin wich doesn't take cache into account

Related issues

• Extend authorized_member system to Cases, Groupings and Reports #4538

Checklist

• I consider the submitted work as finished
• I tested the code for its functionality
• I wrote test cases for the relevant uses case (coverage and e2e)
• I added/update the relevant documentation (either on github or on notion)
• Where necessary I refactored code to improve the overall quality
