Draft: Massage initial-time test to exclude issue with geometry update in TTStationHitManager

Rosen Matev requested to merge bypass-TTHit-geometry-update-issue-2 into run2-patches

This is an update of !504 (closed), see there for details.

As I posted on !504 (closed), the RegexpReplacers there seem not relevant any more. However, (because of a fix in LHCbTest, see LHCb!2410 (merged)) there are some newly exposed differences, shown below. Note that the (relative) differences are only slightly above the default sensitivity of 0.0001 (and for Muon ANN PID the differences are within the sensitivity).
