a187336830 rpc/server: fix error reporting in Start
This error message makes no sense when shutting down the server:
2020-06-25T19:29:53.251+0300    ERROR   failed to start RPC server      {"error": "http: Server closed"}

And ListenAndServer is documented to always return non-nil error one of which
is http.ErrServerClosed. This should also fix the following test failure:

2f8e7e4d33 native: fix getvalidators to match C# implementation
ValidatorsCount is not initialized at block 0 with C# node (the first voter
initializes it) and until that initialization happens the standby validators
list is being returned as is without sorting.

Fixes state mismatch for the key ffffffff0e00000000000000000000000000000001 in
the first blocks.

It also affects tests as now the first validator is different and it receives
the network fees.
