Fix decoder crash with supertx

xd->plane[0].n4_h and xd->plane[0].n4_w are not set at that point
when using supertx.

While this fixes the immediate crash described in the referenced
bug report, there are still issues in the ref-mv experiment that
causes these tests to fail, so they are kept disabled.
