Include all addresses taking part in transactions in wallets' addresses counter

[vbaranov]

Motivation

Wallets counter on the main page accounts only addresses with non-zero balance of native coins.
It should account addresses with zero coins balance too. After all, address can have zero coin balance but own some tokens.

Changelog

Wallets counter on the main page accounts all rows in the addresses table

• I checked whether I should update the docs and did so if necessary
• If I added/changed/removed ENV var, I should update the list of env vars in https://github.com/poanetwork/blockscout/blob/master/docs/env-variables.md to reflect changes in the table here https://poanetwork.github.io/blockscout/#/env-variables?id=blockscout-env-variables.
