Parse obj methods as proto_bare

I don't know if this is the right thing to do, but it works
and it lets 'fn' always mean proto_bare

Fix the problem with check-fast randomly failing
...
Trans has been assuming that tag node id's are unique across crates and they
are not so, depending on which way the wind is blowing, it would choose to use
a crate-local tag variant instead of the correct one from std.
No test case since I can't come up with a reliable one that compiles in a
reasonable amount of time.
