BB10: Clean up IMF session code

Be more rigorous about checking if we're in a session before invoking IMF functions.  In
particular the code would call initEvent if a key was received while no text field had focus
leading to a crash.

Also closeSession is now always called when a session is terminated rather than just
setting sInputSession to 0 and hasSession is always called to check for a valid session.
