Adding stack trace to more calls of _sendError.

[T0bst3r]

Hey there dear team

I hope this is the right way to be doing this, if not, or if I missed out on important information, please let me know.

Here I am adding stack trace to more calls of _sendError with the help of records as hinted in #667 (comment).

This should allow for more accurate logging and debugging of issues in custom errorHandlers.

I have signed the document at least 4 times by now, it always tells me that it's accepted it and redirects me to my other pull request (#667) but the status here does not change. Emails of both PRs are identical. What can I do?
