Commento: anonymous comments are not imported

[mdibaiee]

Hello,

Thanks for remark42, it is a great project!

I've migrated from Commento, and I realised there is an issue with importing comments from anonymous users. The issue is that commento's exported JSON does not include a commenters record for anonymous, so remark42 is filtering out comments from commenterHex: anonymous.

To resolve it, I manually added this to my commento export file:

{"commenterHex":"anonymous","email":"","name":"Anonymous","link":"undefined","photo":"https://remark.my_domain/api/v1/avatar/4fc47f9181a4d5f60537ffbdc28840f475a8fee3.image","provider":"commento","joinDate":"2021-11-06T22:27:46.633536Z","isModerator":false}
