Update views fix for android

When `OT.updateViews()` is called before the session is connected, the video does not work on android (on iOS it works fine).

This pull request fixes this issue by checking whether the session is connected, and only then will it update the view for publisher.

Notes:

Logcat output when updating view before session is connected:
