Null PMC access in Rakudo when running --target=parse on a file with a class declaration

Rakudo e61569f has problems parsing class declarations​:

$ cat A.pm
class A {
}
$ perl6 --target=parse A.pm
Null PMC access in find_method()
in Main (src/gen_setting.pm​:0)

This is kinda strange, because it can produce later stages without a
problem. Probably a PCT bug.

I'm guessing the above fails because --target=prase doesn't make use of
any action methods, and Rakudo's parser really needs the action methods
in order to parse properly. (This will largely change when we become
more STD-like.)

Currently PCT chooses to not send the action grammar along as part of
--parse because it assumes you only want the parse tree (and that parse
tree generation will be independent of action methods). But I can see
places where that might not be the case, so perhaps PCT should always
send the action methods along as well. I'll have to think about it a bit.

works now; resolving without spectest because --target=parse is not specced.
