empathy_status_icon_new: always call status_icon_set_visibility
empathy_status_icon_new: always call status_icon_set_visibility

Seems calling gtk_widget_show() doesn't mark the window as active right away.
This code used to work fine before but doesn't since we replace
empathy_main_window_show() by empathy_main_window_dup().
