Allow exception details when sending error

[nirizr]

This change allows calling sendErrorResponse with an exception (instead of a string) to include exception details within the returned error. This helps in debugging issues, while currently keeping the existing behavior with no change.

Ideally replacing message in calls to sendErrorResponse with the exception object will make error responses easier to understand.

Exposing the additional details may be a bit insecure, so it's smarted to control with a debug flag.

This implementation leaks internal data to the world. Full data captured by pino and a service owner is able to provide it per request. Sorry, i can't give the PR a go.

Thanks for taking your time. I'm fully aware of the internal info exposed (as mentioned in my last sentence).

If there's a builtin way to get the entire trace for an exception i'd gladly use it.
Can you point me into retrieving that info from a wwebjs-api instance I'm running? Thanks!

@nirizr better later than never, so i pushed a commit with error tracing for all exceptions that could arise on controller level 4e2f591
