715bc1af66 test: check `masternode winners` before and after mn_rr (UdjinM6)
9d47cd2226 fix: adjust payee predictions after mn_rr activation (UdjinM6)

Pull request description:

  ## Issue being fixed or feature implemented
  Payment predictions in GUI are wrong when mn_rr is active, `masternode winners` RPC is affected by the same issue too. Actual payments aren't affected.

  ## What was done?
  Adjust calculations, add tests for `masternode winners`.

  ## How Has This Been Tested?
  Run dash-qt on testnet, check "Next Payment" on "Masternode" tab. Run tests.

  ## Breaking Changes
  n/a
