log-tree: call load_ref_decorations() in get_name_decoration()

Load a default set of ref name decorations at the first lookup. This frees direct and indirect callers from doing so. They can still do it if they want to use a filter or are interested in full decorations instead of the default short ones -- the first load_ref_decorations() call wins. This means that the load in builtin/log.c::cmd_log_init_finish() is respected even if --simplify-by-decoration is given, as the previously dominating earlier load in handle_revision_opt() is gone. So a filter given with --decorate-refs-exclude is used for simplification in that case, as expected. Signed-off-by: René Scharfe <l.s.r@web.de> Signed-off-by: Junio C Hamano <gitster@pobox.com>
