radiusOfInnermostHit is being computed using 3D information

[jmcarcell]

As @gaede said here, radiusOfInnermostHit shouldn't be computed using 3D information which is happening at least in

ForwardTracking/src/ForwardTracking/ForwardTracking.cc

Lines 1327 to 1328 in bd6ef3f

	const float* p = trkStateFirstHit->getReferencePoint();
	trackImpl->setRadiusOfInnermostHit( sqrt( p[0]*p[0] + p[1]*p[1] + p[2]*p[2] ) );

and

ForwardTracking/src/ForwardTracking/SiliconEndcapTracking.cc

Lines 1470 to 1471 in bd6ef3f

	const float* p = trkStateFirstHit->getReferencePoint();
	trackImpl->setRadiusOfInnermostHit( sqrt( p[0]*p[0] + p[1]*p[1] + p[2]*p[2] ) );
