bug: unused modified encoded_evals in the test for RS

[romanzac]

Problem

I've noticed altered "encoded" variable was not used during test for RS. When I used it again, the test is failing.

Impact

Test case: occurrence high, impact low.

Expected behavior

Either to rewrite test or explain why decoding with omitted evaluation points from encoding phase produces different result.
