fix: change mmproxy to select new monerod on error

[SWvheerden]

Description

Make sure the MMProxy does select a new node on error

Motivation and Context

Its possible for the monerod to error out on SSL, but not send back and error. The MMProxy then gets this error and keeps retrying the node:

ERROR Method "getblocktemplate" failed handling request: MonerodRequestFailed(reqwest::Error { kind: Request, url: Url { scheme: "https", cannot_be_a_base: false, username: "", password: None, host: Some(Domain("xmr.grub.net")), port: Some(18089), path: "/json_rpc", query: None, fragment: None }, source: hyper::Error(Connect, Ssl(Error { code: ErrorCode(1), cause: Some(Ssl(ErrorStack([Error { code: 167772294, library: "SSL routines", function: "tls_post_process_server_certificate", reason: "certificate verify failed", file: "ssl/statem/statem_clnt.c", line: 1889 }]))) }, X509VerifyResult { code: 18, error: "self-signed certificate" })) })

On Any error the MMProxy will now select a new monerod from the list it has.
