Email alerts for new comments aren't sent

[ToddRowan]

Using Stream 3.2.2 and I set an email alert for new comment submissions.

But no emails are sent, even though Stream captures the comment submission in its log.

The offending line appears to be here. The trigger_context on the alert_meta is comments, but the context on the recordarr is post.

Because of this check_record in class-alerts.php returns false, send_alert is never called, and no email is generated.
