Class Overview
This upgrade task comes with a little bit of history. We started with two indexes on `entity_property` table, these
indexes were entityproperty_entity(entityName, entityId) and entityproperty_key(propertyKey). When developing entity
properties during JIRA 6.2 we created entity_property_identiti(entityName, entityId, propertyKey) to assure that the
search on these three columns is performing well. However, we didn't drop the entityproperty_entity and
entityproperty_key until late phases of 6.4 developments. The drop run on OD and for clients who upgraded to 6.4.0
(the drop was called UpgradeTask_Build64013). Which is when we discovered that this was actually wrong and we have to
restore entityproperty_entity(entityName, entityId) entityproperty_key(propertyKey) and drop the
entity_property_identiti. UpgradeTask_Build64013 is removed so it doesn't run for clients who didn't do the upgrade.
This upgrade task completes the cycle and restore the order two indexes on (entityName, entityId) and (propertyKey).
