chore: add tolerance to tests comparison (#810)

## 🔧 Problem

We have differences in results between local computer and server-ci.
Maybe because of processor architecture (arm64 vs x86).
As a results tests are failing either in local or on server-ci

## 🍰 Solution

As a temporary fix, allow more tolerance in tests floating points
comparison. Going from 1e-16 toleranc to 1e-12 seems reasonable and fix
my tests.
