MuonCombinedRecExample: In MuidMaterialAllocator set TrackingGeometrySvc to null by default
See ATLASRECTS-7268 for discussion (this alone will not completely fix the issue).
I tested this locally with the q449 CA/old comparison test (if this changes the output, then I would expect to see it there).
No changes were detected.
