[BASOP CI] test 26444

There was some sort of merge error in the tests/test_26444.py, used in the BASOP CI. It works in the BASOP CI, but gives an error if you use it with MLD, PEAQ and SSNR.

Now, the ref and test is reversed by default. For the comparison in sa4/audio/ivas-basop#891 (closed), where the EVS BASOP is compared to EVS float, this is the correct order. For checking EVS bit-exactness in the BASOP CI, this is not used and does not matter. If you want to test a codec measuring MLD etc with 26.444 as reference this is not correct, though. I was considering adding an option in conftest.py for this, but it seems like we do not want to many switches in there.
