Don't delay batch offset commits

When `idleBetweenPolls` was set, the sleep was done after invoking
the listener and before calling `pollAndInvoke()` again.

This delays committing the offsets for ack modes other than `RECORD`.

Move the sleep to after committing the offsets and before the next `poll()`.
