disable_spend_updates causes error - User API key and team id and user id missing from custom callback.

[hula-la]

I noticed that when disable_spend_updates: True is set, the system raises "User API key and team id and user id missing from custom callback." error. Since the purpose of disable_spend_updates is to disable spend tracking, I'm wondering if this error is intentional or if it should be handled differently.

Current Behavior

When disable_spend_updates: True:

1. _should_track_cost_callback()(code) returns False
2. _PROXY_track_cost_callback() raises an exception instead of silently skipping (code)

Thank you:)
