[core] TypeError: Cannot read properties of undefined (reading 'name')

I came across this bug in a random test.
https://github.com/haraka/Haraka/blob/f4cc2a61dc3b55b919451a010d5b2fee063e9728/plugins/mail_from.is_resolvable.js#L73
It seems that _this_ is used in the wrong context when catching an exception.
