[perl #123114] [BUG] Enum members not exported with enumeration itself in Rakudo

[Christian Bartolomaeus via RT]

I added a test to S12-enums/misc.t with commit 
https://github.com/perl6/roast/commit/c8e2a0c051

Also I merged RT #111512 into this ticket, since it was about the same problem.

I'm closing this ticket now.
