Poor errors formatting

[0x009922]

Description

tl;dr: Iroha has detailed errors internally, but when it comes to their formatting most of the details are dismissed.

In order for formatting to work properly, each separate Error in Iroha codebase must implement it properly and consistently with others. Since there are quite many Errors, I propose to significantly increase test coverage of their formatting.

Here is an example of this issue: #4973

Detailed error messages are very important for UX. Improving it should not be a breaking API change.

Just another case from users:

ERROR iroha_core::snapshot: Failed to create a snapshot of state error=Error (de)serializing World State View snapshot

We unfortunately will never know what actually happened, although all the details are there inside.

I can work on it.
