Improve logger error reporting

Handler initialization may now call user supplied code in enhancers during
initialization and logging.  This commit catches any exceptions thrown and
uses the existing error reporting mechanism to log the exception the stderr.

The GaeFlexEnhancer now separately logs any exception when obtaining the zone,
but does not throw it as having the zone is only optional and should be non
fatal to the logger.
