*Context*
KStreamsTestDriver allows to build integration tests of KStreamsTopologies. This also includes topologies that sink data into outgoing topics by calling the KStream.to() methods.

*Problem*
When a topic is added as a sink, the KStreamsTestDriver fails with NullPointerExceptions. 

*Solution*
BugFix the method KStreamTestDriver.process() method to also lookup a topic  by topicName as a sink when a source has not been found.

*PullRequest*
