NullPointerException in StripeEntryHandler

Temporary fix https://issues.apache.org/jira/browse/IGNITE-15663 introduced NPE in org.apache.ignite.raft.jraft.core.FSMCallerImpl#runApplyTask, also bug with logging has been found org.apache.ignite.raft.jraft.disruptor.StripedDisruptor.StripeExceptionHandler, exception doesn't been propagated to logger

Solution with NPE is to set true to endOfBatch field in com.lmax.disruptor.EventHandler#onEvent in org.apache.ignite.raft.jraft.disruptor.StripedDisruptor.StripeEntryHandler#onEvent, so we don't need to rely on node.getOptions().getRaftOptions().getApplyBatch()
