The core would create and enqueue data for the Carbon connection even if none is configured. This may incur a small performance penalty and, provided the site generates a large amount of data, log messages such as [carbon connection pool] queue full, didn't push update that are irrelevant.

This fix only sends data to the Carbon connection if necessary.
