Review comment:
writeId will be 0 for non-transactional tables. Also this is
createPartitions code, which may get executed for partitions created when
writeId 0 for transactional tables as well. The condition, which I borrowed
from the old code is required so that we don't create a valid writeId list or
try to get a table snapshot when writeId is zero.
