Dialer: fix wrong visible status of voice search button

When user enters dialer main screen, it will prepare and check
whether should show voice search button, but after back to non-search
mode from search mode, it ignores to check and so the button status
become wrong.

We add to check whether should show voice search button in visibility
updating function.
