[gnome-builder] symbol-tree: don't remove our previous button children

[Christian Hergert <chergert src gnome org>]

commit 9a1433efb7a874719882839dfccf1af55ebf1e1b

    symbol-tree: don't remove our previous button children
    
    We manually track the state now in GbpSymbolMenuButton so there
    is no reason to change the label here and cause those children
    to be removed.
