With same email address, 68566305 still get created with new venmo donation, need to update the logic to honor the venmo external id
- if venmo user id and email match, return oldest cid
- if no venmo user id before but a venmo donation, do not check the firstname lastname, email is sufficient already return oldest cid
- We were getting @xxxx for our venmo id with braintree venmo, while Gravy do not return @ in front, add to gravy (add a logic to check if venmo user name do not have @ add it)
