pipeline should immediately fail with ERR_STREAM_DESTROYED when any of the streams have already been destroyed.

Readable might need a little extra consideration since it's possible to read the data after being destroyed. Should maybe check _readableState.errored and/or _readableState.ended.

Accounts.forgotPassword callback with an error message"User not found [403]" if the user with the specified email does not exist.

Describe the bug

instructions for xframe indicate `ALLOW-FR
