Elements. Update test expectations format for future element / fragment changes.

Most significant changes:
1. Don't write "reference" for fragments, they will not have it.
2. Write `#F<num>` for fragments as unique identifiers instead.
3. Where we used to write "xyz#element", pretend that there is actual element reference, because the next CL will give it to all non-local elements.
