[light/jsonrpc] Provide the actual account for eth_coinbase RPC and unify error handeling for light and full client (#9383)

Browse Source 
* Provide the actual `account` for eth_coinbase

The previous implementation always provided the `zero address` on
`eth_coinbase` RPC. Now, instead the actual address is returned on
success or an error when no account(s) is found!

* full client `eth_coinbase` return err

In the full-client return an error when no account is found instead of
returning the `zero address`

* Remove needless blocks on single import

* Remove needless `static` lifetime on const

* Fix `rpc_eth_author` test
