fixed the fee logic, as the value provided is comulative

[linkielink]

This PR fixes the logic of last24HourFees. The endpoint for the fees returns cumulative fees, not daily fees. Thus, the previous day has to be deducted from the current day.

I ensured this change is also time-machine backward compatible (to clean up already indexed fee data).
