Added a null guard to UpdatePreference.showStyle().

A NullPointerException (and application crash) may occur, when a new
version of Cyanogenmod has been fully downloaded and the ui style should
be altered. It happens when the
activity is resumed and onNewIntent() and UpdatePreference.showStyle() is
called. Since onBindView() has not been called, the view variables are still null and their styles may
not be altered. This patch adds a log warning returns when this happens.
