Add backtraces and more verbose error

[corentinmusard]

When using for exemple node ace db:seed, in case of error you only get a red sentence (often not explicit for newcomers) with no context, no line number, no backtrace.

It's really a nightmare to debug this.

Could you add at least a --verbose flag to show backtrace?

Makes sense. Lemme add it to the roadmap
