pallet-migrations: fix index access for singluar migrations (#5695) 



Discovered a bug in the migrations pallet while debugging
https://github.com/paritytech/try-runtime-cli/pull/90.
It only occurs when a single MBM is configured - hence it did not happen
when Ajuna Network tried it...

Changes:
- Check len of the tuple before accessing its nth_id
- Make nth_id return `None` on unary tuples and n>0
