Motivation: We did miss to use MessageFormatter inside LocationAwareSlf4jLogger and so {} was not correctly replaced in log messages when using slf4j. This regression was introduced by afe0767e9c150369cd6ea150b5cc1a9021fd5c3c. Modifications: - Make use of MessageFormatter - Add unit test. Result: Fixes https://github.com/netty/netty/issues/8483.
