AddConstraintsToIssueAssigneesTable#up

When using the methods "add_concurrent_index", "remove_concurrent_index" or
"add_column_with_default" you must disable the use of transactions
as these methods can not run in an existing transaction.
When using "add_concurrent_index" or "remove_concurrent_index" methods make sure
that either of them is the _only_ method called in the migration,
any other changes should go in a separate migration.
This ensures that upon failure _only_ the index creation or removing fails
and can be retried or reverted easily.

To disable transactions uncomment the following line and remove these
comments:
disable_ddl_transaction!
