[Partial Undelegate] The amount of the second partial undelegation is always in pending_undelegation_amount and cannot be withdrawn

[NellYao]

Summary of Bug:

The amount of the second partial undelegation is always in pending_undelegation_amount and cannot be withdrawn

Version: Exocore 1.0.9

Environment: Four validators built locally, without Oracle
Precondition:

• Perform operations such as deposit, delegation, partial undelegate, withdraw on the node with a voting power of 2700 and query the changes in voting power, asset info of staker
• Set epoch as minute

Steps to Reproduce:

1.Deposit 1000 ETH at 0:00:03(h:mm:ss)
./assetcli deposit --rpcUrl http://localhost:9545/ --staker 0x622869A3a10261019f88B64D312d0B8a77855390 --amount 1000000000000000000000 --privateKey 3EB1BDCCBACC8D5672918009F3F546EDC09E81BC0B58514C907D1C8C7E149352 --defaultAssetID 0x83E6850591425e3C1E263c054f4466838B9Bd9e4 --layerZeroID 40161

2.Delegate 1000 ETH at 0:00:22(h:mm:ss):

Simpler version of reproduction steps:

1. Setup four validator nodes. (https://github.com/cloud8little/ExocoreValidators)
2. Put node folders under /root/testnetV6 or update the oracle_feeder.yaml configuration to use the absolute path of node config folder.
3. Use exocore v1.0.9.
4. Run ./clean.sh
5. Run ./copy.sh
6. Use assetsTool to run deposit/delegation.
7. Run a partial delegation.
8. Run a second partial delegation.
