Enable Contextual Identity support for SessionRestore

Contextual Identity support for session restore was disabled by bug 1195881 so that we can have contextual identity running under e10s. Enabling the SessionStore to restore the userContextId causes a crash under e10s. See for the crash.
This part looks bad:

Sorry smaug but if you can review this patch again...
The previous one was breaking a test because we were resetting the userContextId all the time we where adding a new docShell child.
In this patch I added a check and we don't update the userContextId in case the current one is != 0.

I don't understand the new patch. If the original patch causes issues, that feels like a bug in the 
code using the API.

So I don't see why we want to break the consistency in the API.

You could just move the new code under this 'if() {}' and then
call childDocShell->SetUserContextId(mUserContextId); without if-check

Drop this if. No need for special casing what UCI type
