Bug 914100 - [SMS][keyboard] keyboard disappears after typing ; for the contacts when typing multiple contacts

- Recipients.View
    - Had a race condition between render() and focus() because of calls within render() which were asynchronous.  Separated out the calls after a ';' is typed to wait for render() to finish before calling focus(), which causes the keyboard to reappear (or not disappear).

    - Integration test needed?
