minor fixes in ST in espnet2

[siddalmia]

This PR does some minor bug patches to the PRs - #3987 and #4013

• the DB had some errors and redundancy.
• st/espnet_model.py had errors in their logging.
• egs2/iwslt22_dialect/asr1/run.sh asr config file path was wrong.
• egs2/fisher_callhome_spanish/st1/run.sh is also broken. I am still working on this. @ftshijt would you like to have a look at this? I have sent you the error.

Hi @sw005320, please don't merge it yet. There are still a lot of broken files in the egs2/fisher_callhome_spanish I found both asr1 and st1 to be broken.

[siddalmia]

Ok ready to merge. @sw005320
