Description

Kafka Consumer Component configured with 

• autoCommitEnable == false
• allowManualCommit == true
• autoCommitOnStop == none

always commits the last seen offset for every partition when route is shut down.

What's happens is the following:

1. consumer.unsubscribe() is called
2. onPartitionsRevoked() is called
3. commitOffset() with forceCommit == true is called
