[TRAX] Fixing a few OSS test errors (There maybe further errors, but …

…this is good to go):

 - ConfigTest needs to iterate on .gin and not .gin + .yaml
 - `if dm_suite` then set eval_env and env to None, otherwise ConfigTest complains.
 - Explicitly pass in extra_ids to t5's SPC vocab - otherwise is computes with None.
