Typo in DB index schema

[Pandry]

I was giving a look a the index script, and it looks like there's typo here:

trex/platforms/yttrex/backend/scripts/build-indexes.js

Line 63 in 7793254

ret = db.experiments2.createIndex({ experimentId: -1, unique: true });

I think it is supposed to be ret = db.experiments2.createIndex({ experimentId: -1},{unique: true });

Also I'd love to rename the collection from experiments2 to experiments
