Anna Shaleva 2c46b81864 native: optimize gas per vote calculation
GAS per vote records are being returned from Seek in ascending way, and
we need the last record before the specified index which is close to
the current chain's height (most of the time). To optimize we can
iterate backwards strting from the last record using SeekBackwards.
