Auto merge of #2985 - flba-eb:fix_s_macro_order, r=JohnTitor

Enforce order of any `s_*!` macro calls

Before this change, only the order of `s!` was checked. After, it also checks `s_no_extra_traits!` and `s_paren!`. Only the order is checked, not the number of calls. This is required because multiple calls have to be allowed.
