Pull request description:

  #12953 inadvertently removed the functionality to call `getbalance "*" <int> <bool>` to get the wallet's balance with either minconfs or include_watchonly.

  This restores that functionality (when `-deprecatedrpc=accounts`), and also makes it possible to call ``getbalance minconf=<int> include_watchonly=<bool>` when accounts are not being used.
