Remove stacktrace from database errors

[3fonov]

Summary

I'm always frustrated when scrolling throw stack trace to my actual errors in database.

#381

Solution
Remove stack trace and keep only database errors.

Hi @3fonov

Thank you for your contribution!
I'm not sure this behavior would be desired, as we often use the stack trace to investigate CH side issues.

In addition, usually, the error appears right at the beginning of the stack trace, so in what case do you need to scroll to find it? You can just ignore the reset of the lines.

I understand that it might be frustrating for you to have irrelevant text, but it is crucial for many other users.

We would love to get your help with other critical issues in this repo.

Thank you again for your contribution.

@BentsiLeviav added ENV VAR to control behavior and corresponding tests.

[BentsiLeviav]

Could you please fix the lint issue?

Could you please fix the lint issue?

It seems that it is from file that i didn't touched: tests/integration/adapter/dictionary/test_dictionary.py. Fixed it anyway.

Ohh thanks for that!
