Reset settings button when update the list view.

Reset settings button when update the list view.

We need to reset the settings button object when updating the IME detailed view, otherwise there may has memory leak, and checking if(settings_button_) could be true but the IME view is updated without drawing the settings button.

BUG=667105
TEST=Verified on Clapper.
