expose hold, unhold and blind transfer

about #13

I tried to make a few tests using the demo numbers (the ones available on the app by npm start) but I couldn't... the hold fails and cancels the call, while the transfer says that REFER is not allowed.

Hi @Mazuh I found a problem where hangup is not working anymore in index.html

You can reproduce by calling Freeswitch and trying to hangup

stable :
https://demo.webrtc.flowroute.com/fr.html?cache_invalidate=xxx
this branch :
https://demo.webrtc.flowroute.com/dev.html?cache_invalidate=xxx

When I try to hangup, are you not facing the same problem ?
I copied index.html

dev.html?cache_invalidate=xxx:141 Uncaught TypeError: Cannot read property 'call_id' of null
    at FlowrouteClient.handleCallAction [as onCallAction] (dev.html?cache_invalidate=xxx:141)

I confirm the error

@Mazuh sorry I did not notice that you where having hard time to test on our servers.
We may need another server in staging.

@Mazuh is you can fix the problem with hangup @prinze77 could test the feature, I will simply test that there is not regression, we will most likely not support REFER in the near future.

Does this makes sense to you guys ?

Testing the feature

Looks like blind transfer, mute and unmute works perfect.
@jchavanton what you mean you will stop the support of REFER then how
I finished the first stable version of UI that we talked earlier https://github.com/prinze77/react-softphone
If we implement attended transfer and call queue of hold 3 calls i will use this lib in https://github.com/prinze77/react-softphone.

What I meant is that our provided server side infrastructure is not and that we will not support it soon enough to validate this new feature on it.
However, we want to make sure existing features are still working well before merging.
Thanks for your testing, hopefully this feature will be in soon.

Thanks for sharing you UI
