This upgrade task adds new scheme entities to the eventIdDestination of all notification schemes in JIRA. It uses
the eventIdSource scheme entities as a template for what to create.
For example UpgradeTask_Build207 uses this to grant the Comment Edited notification event to all entities who
currently have the Issue Commented event.
