    Fixed first character eating
    
    Search "entry_changed" and groups "treeview_changed" callbacks were
    calling (indirectly) each other: text changed cleared tree selection, tree
    changed cleared text entry.
    
    Changed gpk_application_groups_treeview_changed_cb to clear text
    only if selection exists.
    Changed gpk_application_text_changed_cb to clear selection only if text
    is empty.
