When querying the delegatable energy share of an account, if the available energy share in the account is 0, this API returns {}
When querying the delegatable bandwidth share of an account, if the bandwidth obtained by staking in the account is not enough to pay for the bandwidth consumed by a resource delegation transaction itself, this API also returns {}

I wonder if we should return 0 in such cases
