DefaultHttpCoordinator.SetFunctionContextAsync throwing InvalidOperationException

[jviau]

Description

Customer reporting intermittent issues with their HTTP triggers throwing an InvalidOperationException due to calling SetResult on an already complete TCS. I believe we have a race condition between preparing the HTTP invocation and a timeout / cancellation.

Line 48 in 16fe6c6

contextRef.FunctionContextValueSource.SetResult(context);

Steps to reproduce
