WebsocketProvider event emitter problem

[boomfly]

Description

WebsocketProvider.on 'connect' event stop occur after first time and does not fired after next socket connect, subscriptions not resubscribed too.

Expected behavior

provider = new Web3.providers.WebsocketProvider(wsUrl, options)
onConnect = () => console.log('connected')
provider.on('connect', onConnect)

onConnect callback should be called after each websocket reconnect

Actual behavior

onConnect called only once on first connect

Steps to reproduce the behavior
