KAFKA-5003; StreamThread should catch InvalidTopicException 

We should catch `InvalidTopicException` and not just
`NoOffsetForPartitionException`. Also, we need to step through
all partitions that might be affected and reset those.

Author: Matthias J. Sax <matthias@confluent.io>

Reviewers: Bill Bejeck <bbejeck@gmail.com>, Eno Thereska <eno@confluent.io>, Damian Guy <damian.guy@gmail.com>, Ismael Juma <ismael@juma.me.uk>

Closes #2747 from mjsax/minor-fix-reset
