fix: save DB with with query

[betodealmeida]

SUMMARY

Databases are not saving because we're sending query as a string due to the incorrect check.

This fixes the problem, but I think we should spend some cycles improving state in the frontend. Having query be a string sometimes, and an object other times will certainly lead to more bugs.
