Fix Muon TSOS sorting (ATLASRECTS-4923)
The TSOS sorting was previously using Identifier comparisons as the first step in sorting. However, these do not work for holes, which have no Identifiers by design. This fix only uses Identifiers to sort in the case that neither TSOS being considered is a hole.
