Comments: Validate new comments before and after comment data is filtered. 

This ensures that a Disallowed Comment Keys match will consistently send the comment to the Trash, by checking both the original unmodified comment data and the final filtered comment data.

If the first check has already resulted in a `trash` or `spam` status, the second check is skipped as redundant.

Follow-up to [2894], [3851], [48121], [48575].
