Since program-test creates a test genesis and then adds fees and rent,
some of the genesis accounts get rent-collected after warping. Most
notably, `StakeConfig` gets rent-collected, causing any stake operations
to fail after warp. This fix creates genesis with the `Rent` and
`FeeRateGovernor` actually used by the bank.
