Problem
The system chunk panics when ending the staking auction, when running epoch integration tests using the version of flow-core-contracts in the node-lists branch.

- In the test case, one new Collection Node stakes and an existing Collection Node unstakes, at the first epoch boundary.
- The error first appears at height 197, which corresponds to the staking auction end view of 199 -- so this failure occurs at the end of the staking auction.
Steps to Reproduce
Run test TestEpochJoinAndLeaveLN on branch onflow/flow-go#3837, which uses the modified Staking contract.
