When we could get MissingNodeException?

Mainly during fast-sync.

It could happen during regular one if state node is lost along the way, but it's much less probable while during fast-sync it is sure that such error happens.

Minor: I would like to name this function toResponse or sth similar and reformat the code to
val account = blockchain
.getAccount(address, block.header.number)
.getOrElse(Account.empty(blockchainConfig.accountStartNonce))
toResponse(account)
it is a little bit more readable

Description
Report custom eth error "100 missing data" when getting data from account
Proposed Solution
implementation of https://eth.wiki/json-rpc/json-rpc-error-codes-improvement-proposal (at least in account-touching methods)
Important Changes Introduced
Reorganized a bit json serialization. Due to nasty error I run into at some point (json4s and its formats <3) I wanted to plug Encoder-based serialization into rpc servers, due to multiple issues I stopped that and got into working state
Testing
Call methods like
eth_getBalanceduring fast-sync - it should return error with additional information that state node is missing
