Fix duration=0 & stream disabled bugs

[hmstepanek]

Overview

Fix the following bugs in openai:

• During errors, the function trace is not exited before capturing the duration so the duration=0 inside the events.
• When not streaming but stream monitoring is disabled, the function trace is exited early and events are not recorded.
