fix: display only the error message for sql-editor

fix #3132

I would say the "stack" error makes more sense if you're in developer/debug mode

[alecsci]

Not sure if it's worth doing that much implementation to hide some technical info. I would like to keep the error component dumb as possible.

We could show both information, but put first the error message, and then the last field can be the stack trace. @FrancescoBorzi wdyt?

We could show both but in a separate way, so the user can focus on the error message first and then if it's useful can also read the stack.
