Remove RUN_INDEX from single tests
This is a fix for #447 (closed).
The test.yaml
for a couple of the directed debug tests had a TEST_INDEX post-fix in their name. I cannot understand why, but this only affects Riviera-PRO. This fix cleans things up and works with dsim and xrun. In order to test that the problem goes away using Riviera-PRO I needed to stub out the simulator, but I can confirm that the original issue reported in #447 (closed) shows up using these stubs and goes away with the update on this branch.
