self_test_ltv inconsistencies

One test case in self_test_ltv.prm seems to be duplicated:

https://forge.3gpp.org/rep/ivas-codec-pc/ivas-codec/-/blob/main/scripts/config/self_test_ltv.prm#L1218-1220 https://forge.3gpp.org/rep/ivas-codec-pc/ivas-codec/-/blob/main/scripts/config/self_test_ltv.prm#L1237-1239

The STV tests specify 1dir/2dir for MASA tests, while it is missing for LTV tests.
