[NFC] Test cleanup to stop calling Email::add action which does not handle primary

[NFC] Test cleanup to stop calling Email::add action which does not handle primary

Note I feel like we should further
1) move the contents of email add into create
2) make add a deprecated wrapper for create

Whatever the vision of different add vs create functions it didn't turn out in practice and seems to
only generate confusion. We recommend apiv4 as the preferred create methodology
