Fix issue where syncing to latest causes all multifile projectX builds to fail

- Issue was that our algorithm for computing equivalence between the ILToc and the thing we are compiling was using a string which was supposed to be unique per type
- Unfortunately, it wasn't in the case of nested types nested in other nested types
- Fix is straightforward, simply use AppendName instead of AppendNameForNamespaceType for the containing type.
