Bug Description

I recently wanted to make an API tuned version of Bug.attachments; Bug.attachments is used in several places, and many of them do not need prepopulation; so I wanted to say
attachments_prepopulated = exported(CollectionField(...), exported_as='attachments')
attachments = CollectionField(...)

But I got 404's doing this. Adding doNotSnapshot just in case (because exported_as on a CollectionField is working for person/participations) didn't help.

I think this is a bug in WebServicePublicationMixin.traverseName Either the traversed name is the wrong name for entry.schema.get(name), or it's the wrong name to pass in to _traverseToScopedCollection. I can't figure out which, because even though I'm fairly certain this is where the bug is, the code looks correct to me--the mapping from the external name to the internal name should happen inside the entry object. It should be easy to see the bug in action by putting a breakpoint in traverseName.
