When the pledge amount of the verification node list is the same, the node ranking order is wrong

[qiusese]

PlatON version: 0.13.1

1、Pledge two nodes with the same amount
2、Inconsistent pledge block height
3、The ranking order of pledge nodes is wrong

[cheng762]

this is a bug,When the version and amount are the same, they should be sorted in the order of pledge
