rpcsrv: align default error code with C# implementation

Browse source 
We had 400, 405 and 500 in getHTTPCodeForError, but none is explicitly
set in C#.

1. **405 code** (unknown method, `neorpc.MethodNotFoundCode`). The
resulting HTTP code returned by C# server is 200 OK:
```
anna@kiwi:~/Documents/GitProjects/bane-labs/go-ethereum$ curl -v -d '{
"jsonrpc": "2.0", "id": 1, "method": "unknown-method", "params": [] }'

2. **400 code** (malformed request, `neorpc.BadRequestCode`). The
resulting HTTP code returned by C# server is 200 OK:

      "message" : "Bad request"
   },
   "id" : null,
   "jsonrpc" : "2.0"
}
```
3. **500 code** (internal server error, `neorpc
.InternalServerErrorCode`). It's difficult to reproduce this error on
real network for C# server, but the resulting code is expected to be the
 same, 200 OK.

Close #3586
