Fix #macro? for numblock nodes

We can have macros in numblocks. I found this issue while working on
broader `numblock` nodes support for cops in rubocop and found out that
the`#bare_access_modifier?` method was not giving proper results for
modifiers in numblocks. This applies to other methods that depend on the
`#macro?` methods.
