SAT: make property removal in a stream fail backward compatibility testing

[alafanechere]

Tell us about the problem you're trying to solve

We considered until today that property removal is not a breaking change as Normalization is not destructive and will not delete the removed column.
But from a record consistency standpoint removing a field leads to record with "fewer" data.

Describe the solution you’d like

• Detect field removal in SAT discovery backward compatibility test.
• Make the test fail if a field was removed

An new assertion needs to be added to this function.
