PROTON-772: Remove all direct printing to stdout and stderr (missed one)

Added a check to ensure we don't log any transport trace messages unless at 
one of the trace modes is enabled.

> A library should never, ever print anything directly to stdout/stderr unless 
> explicitly requested to do so, as it may be linked with programs that need to 
> control what they output to stdout/err or programs that have no stdout/err at 
> all.
> Failures should be raised  via the API error mechanism with appropriate 
> message strings that the caller can display as they see fit. Informational 
> log messages should be logged in a way that the caller can send them where 
> they want or turn them off if they want.
