Bond intra-tx counter not correctly set on stake.InitGenesis

[cwgoes]

Caught on https://github.com/cosmos/cosmos-sdk/tree/8cacb9658402d7c800e24e3f9f93f7d9576a1d75, will write an isolating testcase.

edit: Finally traced to an error with stake genesis initialization. Bond intra-tx counter was set correctly for the power store record but not for the validator record, so when we wrote a new power store record later we left the old record in when we should have deleted it.

Can the resolution for this issue be made as a separate PR onto the simulation PR

Maybe, I think it depends on the resolution of the issue.
