get room owner on event 'room-join','room-topic'

[JasLin]

issue 1:

wxwebApp had hide uin of room members from some routing. so we can't get owner by using uin anymore:

memberList = memberList.filter(m => m.get('uin') === ownerUin)
     if (memberList.length > 0) {
       return memberList[0]
     } else {
       return null
     }

but on 'room-join' and 'room-topic' event ,we got a ``ChatRoomOwner``` property from rawObj, it can be used to load owner..

rawObj:
   { Alias: '',
     AppAccountFlag: 0,
     AttrStatus: 0,
     ChatRoomId: 0,
     ChatRoomOwner: '@b261a88d4de1479cdf735c851fe22afe',
     City: '',
     ContactFlag: 2,
     DisplayName: '',
     EncryChatRoomId: '@dfee772e7d01ad0cfcdc5e2e8c81e558',
     HeadImgUpdateFlag: 1,
     HeadImgUrl: '/cgi-bin/mmwebwx-bin/webwxgetheadimg?seq=0&username=@@72317905edc07327e00aa61f690de1ea2a98117aca6ff32ddfe4eb0&skey=@crypt_9d729d2b_71e57bdd5f75
90fee74da393476f8160',
     HideInputBarFlag: 0,
     KeyWord: '',
     MMFromBatchGet: true,
     MMFromBatchget: true,
     MMInChatroom: true,

issues 2: throw new Error('no user')

when i trying to use https://app.wechaty.io.

reproduce

1. start robot
2. and then opening wechaty.io
3. login
4. robot got error

/home/jas/projects/learning/wechat/wechaty-ts/src/wechaty.ts:127
      throw new Error('no user')
            ^
Error: no user
    at Wechaty.user (/home/jas/projects/learning/wechat/wechaty-ts/src/wechaty.ts:127:13)
    at WebSocket.ws.on.e (/home/jas/projects/learning/wechat/wechaty-ts/src/io.ts:221:45)
    at emitTwo (events.js:106:13)
    at WebSocket.emit (events.js:191:7)
    at Receiver.ontext (/home/jas/projects/learning/wechat/wechaty-ts/node_modules/ws/lib/WebSocket.js:841:10)

    at afterWrite (_stream_writable.js:387:3)
    at onwrite (_stream_writable.js:378:7)

i trace the code . when login in web , it will send a ws event 'update' to robot. and it will call wechaty.user() , at the same time ,because user haven't login ,the wechaty.user() will throw errors.

i change it to wechaty.puppet.user directly . then everything is ok.

Great hack for the ChatRoomOwner property, thanks!

I'll check the new module requirement problem in the package.json, it's my bad.

BTW: app.wechaty.io is using a very early stage WebSocket protocol to communicate with Wechaty Runtime(as I named it: a Chatie), so there will be expected others' problem as well, so please be careful when you are using it.

CI failed becasue I forgot to run npm install @types/request @types/fluent-ffmpeg --save-dev. fixed.
