Headers not sent when pullReplication.Continuous = true

[hackily]

If I'm approaching this the wrong way, let me know!

I have yet to work out the details regarding the sync gateway OpenID Connect implicit flow and getting an ID token, but maybe I should? Anyhow...

Background:
I need to send an auth token in the header with every HTTP request I make to the sync gateway.
Otherwise, I'll get 401s.
(Not sure how the ID token will play into that, the sync gateway is protected a behind a UAA service)

Replication pull = database.CreatePullReplication(uriBuilder.Uri);
pull.Headers.Add("Authorization", "bearer " + accessToken);
pull.Continuous = true;
pull.Start();

If pull.Continuous = true, the trace shows that the headers I added are missing:

System.Net Information: 0 : [18636] ConnectStream#44780731 - Sending headers

}.

On the other hand, when pull.Continuous = false :

Multiple HTTP calls are able to made correctly.

Admittedly, I am using a beta build, but I couldn't get this far with 1.3.1 :)

Well, if it is working with non-continuous and not with continuous that's definitely a problem. This shouldn't be hard to repro and fix though. I'll update after I reproduce it.

The web socket change tracker was not passing the headers from the puller along. This has been fixed now.

P.S. We have some helper stuff for OpenID Connect. You can see details about it here.

Awesome, thanks for the quick support!
