DRICHHits (usually) empty after the change of `sens.setType("photoncounter")` to `tracker`

After !330 (merged) was merged, the DRICHHits branch is usually empty (or there are only a few sporadic entries). If I try reverting the type back to photoncounter, we see the expected distribution.

Using MR !332 (closed) for testing: see artifact test.png from job test_drich

Steps to reproduce (executed from top-level athena directory):

npsim --runType run --compactFile compact/subsystem_views/drich_only.xml --macro test.mac --outputFile test.root --enableG4GPS

where test.mac is

/control/verbose 2
/run/initialize
/gps/verbose 2
/gps/particle pi+
/gps/number 1
/gps/ene/mono 20 GeV
/gps/position 0 0 0 cm
/gps/direction 0.25 0.0 1.0
/run/beamOn 50

Opening test.root and running events->Draw("DRICHHits.position.x") should produce a distribution that looks like the attached image, but is coming out empty (or sometimes a few sporadic hits)

It is likely the pfRICH is also affected.
