* Add consolidate methods * Update distr feepool balance with dust, add tests * Set params for proposal handler to not influence module balances * Add StakingRewardsPerSecond param for proposal test * Update changelog * Update test to check emitted events * Log dust amounts for x/distribution * Modify feepool communitypool field instead of entire replacement * Update tests to include cases with empty balances * Move EventsContains to app * Remove extra copied ModuleName * Add Require() to incentive claims in tests to reduce errors * Move consolidate tests to testutil * Only transfer non-ukava coins * Add DefaultStakingRewardsState to proposal handler test * Move event emit before consolidate * add golangci specific timeout --------- Co-authored-by: Nick DeLuca <nickdeluca08@gmail.com>
