[gedit/gnome-3-0] Fix use-after-free during incremental search

[Ignacio Casal Quinteiro <icq src gnome org>]

commit 5ce4041ba594a5307c4d1632596a95305bc4ca2b

    Fix use-after-free during incremental search
    
    Move the free right before the assignment to ensure that
    old_search_text is never left dangling and thus double-freed
    if init_search_entry() is called again.
    
    Fixes https://bugzilla.gnome.org/show_bug.cgi?id=651068
