Add specific /vaults/bkava and /deposits query handler to get aggregated bkava amounts (#1293)

Browse Source 
* Use custom aggregate handler for querying 'bkava' vault

* Add 3rd bkava vault

* Add special kava deposit handlers

* Separate bkava logic to parent deposits handler

* Rename single vault/account queries

* Remove all deposits queries

* Include empty vaults in /vaults query

* Respond with empty values when querying account deposits with no deposits

* return ukava value in bkava vault queries

* remove refernce to specific staked token denom

* return ukava value in bkava deposit queries
