What is the purpose of the change
Current valset undelegation logic has a bug where it calculates the amount to undelegate based on validator shares instead of their underlying tokens. Since the value of shares are nonfungible and highly variable across validators, this is a fundamentally incorrect way to calculate the correct portion of a valset that corresponds to a given validator. For instance, if a user has delegated 10 shares each to 10 validators and one of the validators gets slashed for 20% of its stake, the current implementation would continue to treat the slashed validator as 10% of the delegator's set.
This PR fixes valset undelegation logic so it works with tokens instead of shares.
