Auto/Manual AAD tests started to be mutually exclusive

[tamirkamara]

Describe the bug
In the night tests we have 2 flows that create workspace with manual and automatic AAD setup for the app registration.
Recent runs show that only one succeeds while the other immediately fails without any details.

The tests are:
test_create_guacamole_service_into_base_workspace
test_create_guacamole_service_into_aad_workspace
