Fix bugs in Tragectory calculations in MD normalization for direct geometry

[abuts]

This ticket is blocks : TRAC9105, TRAC10830

Build LET event workspace using script attached and data files available in system tests Data directory (it will fail with current reduction but usable event workspace LET1_spe will be produced

Then run script below to produce normalization workspace and do normalization.

The picture provided clearly shows that the trajectories calculations is wrong

SetUB(Workspace='LET1_spe', a=2.73, b=2.73, c=2.73)
SetGoniometer(Workspace='LET1_spe', Goniometers='Universal', Axis0='psi,0,1,0,1')
AddSampleLog(Workspace='LET1_spe', LogName='Psi', LogText='20', LogType='Number')
ConvertToMD(InputWorkspace='LET1_spe', QDimensions='Q3D', Q3DFrames='HKL', QConversionScales='HKL', OutputWorkspace='mdWs1', MinValues='-0.1,-0.1,-0.1,-5', MaxValues='1,0.05,0.05,10', SplitInto='20', MaxRecursionDepth=1)
MDNormDirectSC(InputWorkspace='mdWs1', AlignedDim0='[H,0,0],-0.1,1,20', AlignedDim1='[0,K,0],-0.1,0.05,20', AlignedDim2='[0,0,L],-0.1,0.05,20', AlignedDim3='DeltaE,-5,10,20', OutputWorkspace='mdWs1a', OutputNormalizationWorkspace='mdWs1Norm')

DivideMD(LHSWorkspace='mdWs1a', RHSWorkspace='mdWs1Norm', OutputWorkspace='mdWs1b')
