Proxy: a remote hangup should not crash the server

[75lb]

if a remote proxy request fails for some reason (e.g. socket hang-up), ws crashes.. it should handle the exception, report the issue and carry on.

InternalServerError: [PROXY] socket hang up: http://lhtapp01:8180/resources/contents/copies/113864/draft?nocache=146315555730825777655849.375153

Adding a third example:

InternalServerError: [PROXY] connect ECONNREFUSED 127.0.0.1:8080: http://localhost:8080/...
    at Object.throw (/usr/local/lib/node_modules/local-web-server/node_modules/koa/lib/context.js:91:23)
    at ProxyServer.<anonymous> (/usr/local/lib/node_modules/local-web-server/lib/middleware.js:48:17)
    at ProxyServer.emit (/usr/local/lib/node_modules/local-web-server/node_modules/eventemitter3/index.js:144:27)
    at ClientRequest.proxyError (/usr/local/lib/node_modules/local-web-server/node_modules/http-proxy/lib/http-proxy/passes/web-incoming.js:141:16)
    at emitOne (events.js:82:20)
    at ClientRequest.emit (events.js:169:7)
    at Socket.socketErrorListener (_http_client.js:258:9)
    at emitOne (events.js:77:13)
    at Socket.emit (events.js:169:7)
    at emitErrorNT (net.js:1256:8)

ws started with:

ws -p 8082 -r '/api/*->http://localhost:8080/$1' -d app

and the proxied app was not running or had crashed.

fixed and released in v1.2.5, thanks for the patience.
