History is lost after ConjoinWorkspaces

[mantid-builder]

Original Reporter: Gesner Passos

ConjoinWorkspaces will get just part of the history necessary to construct the workspace. This will make the final result not 'reproducible' in the long term.

Out1 = LoadNexus('16183',SpectrumMin=2,SpectrumMax=10)
Out2 = LoadNexus('16185',SpectrumMin=11,SpectrumMax=20)
ConjoinWorkspaces(Out1,Out2,False)

LoadNexus(Filename=r'/archive/ndxsans2d/Instrument/data/cycle_12_3/SANS2D00016185.nxs',OutputWorkspace='Out2',SpectrumMin='11',SpectrumMax='20')
ConjoinWorkspaces(InputWorkspace1='Out1',InputWorkspace2='Out2',CheckOverlapping='0')

There was some discussion on the History and to change its design, so I thought it would be worth to mention this problem as well.
