Update Java driver to include Netty fix

The recent Java driver configures Netty so that it spawns deamon
threads for its event loops and therefore does not block
application when they shut down. This is especially useful for
CLI applications using the JDBC driver.

See neo4j/neo4j-java-driver#918 for more
context.
