Do not treat parent struct as a module for nested structs

This fixes `ItemCanonicalPath` to return paths of the form `[module*,
item]` rather than `[item*, item]`. That is, there will only be module
names before the item's name, rather than also other arbitrary item
names (such as parent structs).

Fixes #311
