remove x/mint (#1416)
* use kavamint in incentive to calculate staking apy

* use kavamint minting: rewards_earn_staking_integration_test

* update incentive tests to mint only with kavamint

* remove x/mint from incentive tests

* remove x/mint from kava app

* fix minting in x/auction tests

* replace simapp fund calls with test helper

* remove mint state from genesis.json
