Fix passing K2 language version to K1 multimodule tests

After splitting K1 and K2 tests some multimodule tests in K1 configuration were still running with 2.0 language version. The reason was in misconfiguration of complex multimodule projects - they don't apply override of compiler arguments. This fix added such arguments update.
