Maintenance: Renamed confusing fields in EmailAddresses table

The EmailAddress model is used to store email addresses used by the system.
It was using realname: field as a name while the rest of the system uses name: for, well, naming objects.
This commit renames email_addresses.realname to email_addresses.name for the sake of consistency.
