fix(ai): remove error logging in sendMessageStream()

[dlarocque]

Removes error logging in sendMessageStream(). These errors are catchable by the user, so there is no need to log them. This removes the anti-pattern of throwing a SILENT_ERROR to skip promise chains.

This fix is important for when we add AbortSignal. Since aborting a request raises an AbortError, every time a request is aborted, there will be an error logged to the console, which is undesirable for the user.
