Not informative log-output for unsupported but valid methods

[oleksandrSydorenkoJ]

Preconditions: Active schain medium type Oracle-demo

Versions: skalenetwork/schain:3.16.1-beta.0

Steps to reproduce:

1. Run oracle demo for eth_gasPrice

   
           '"cid":<skaleChainId>,"uri":"eth://","jsps":["/result"],encoding":"json","ethApi":"eth_gasPrice","params":[]'

2. check output

**Expected state:**
Oracle request should return readable error - not supported method for Oracle. 
For the invalid request Oracle should return the full request line with detailed mistake in request.  

**Actual state:**
Oracle request returns ``message': 'Oracle request failed with status 10'`` error related to [#define ORACLE_INVALID_JSON_REQUEST 10](https://github.com/skalenetwork/skale-consensus/tree/develop/oracle#list-of-oracle-error-codes)

Re-checked on skalenetwork/schain:3.16.1-beta.2 Error-log output is implemented for this version of skaled.

There are unclear responses from Oracle

1. Send oracle request to web2 with bad latency logs from skaled:
