    query-editor: Don't set the entry's text if not strictly needed
    
    If the current text in the entry is equal to the new query's text we
    shouldn't needlessly set the text on the entry since that affects the
    cursor position.
    
    gtk_entry_set_text() already does a similar check internally but that
    isn't enough here because NautilusQuery doesn't keep the full string
    but instead a stripped version of it.
