An invite already exists with lowercase and user invites them again, twice with different casing
An invite already exists with lowercase and user invites them again, twice with different casing, so no current invite was found and new records were attempted to be inserted into the database. One for each instance of the email on the request.
We will only show 'red' on the email token for the last case insensitive instance of that email. In other words, all but the last instance of that email will show 'green' even though they failed to insert to the database.
