Race condition allows 2 customer accounts with the same email to created.

We create Customer Accounts via events.

When 2 events with the same email are processed at the same time, 2 Customer Accounts get created with the same email instead of 1 request failing due to the unique email constraint.

This happens intermittently, and I've been able to reproduced it a couple of times.

Yes, it is possible that more than one customer account with the same email could be created at the same time, as we don't have unique constraint at the database level.
