If you enter the following RFC 2822 compliant address:
`John Doe <john@doe.com>`

Gitlab will attempt to send three emails:
1) John
2) Doe
3) john@doe.com

With this change given the following:
`John Doe <johndoe@example.com>`
`Jane Doe <janedoe@example.com>`

Gitlab will send emails to `johndoe@example.com` and `janedoe@example.com`
