The change added in elastic#6762 helps making sure the pending mapping updates are processed on all nodes to prevent moving shards to nodes which are not yet fully aware of the new mapping. However it introduced a racing condition delete_mapping operations, potentially causing a type to be added after it's deletion. This commit solves this by only sending a mapping update if the mapping source has actually changed.
