    popup-entry: fix direct access issue for entry widget in cell renderer mode
    
    The old code directly accessed a member variable of GtkEntry. This
    direct access will no longer be possible with GTK3, but there is no
    public function to get/set this variable.
    
    Instead use gtk_entry_set_visible as found to be a good enough
    alternative by GnuCash developers who did this change during their
    porting of this code (originally forked from planner) to GTK3.
    
    Matches GnuCash commit 87a0cb736025269821c743d1154cf89656a54b21
