Currency: Remove Pair Index formatting/parsing (#1520)

* Currency: Remove Pair Index formatting/parsing

This feature was originally for exchanges with only one pair (e.g. KRW) which made parsing easier.
However there's no examples of this left, and we can reduce complexity
overall by removing it.

* Exchange: Partial assertify tests and fixes

* Currency: Fix panic on a delimiterless small currency
