SaveNexusProcessed crashes when run twice with a group

[Martyn Gigg]

Run this script to test:

result = "GEM38370"
LoadRaw("GEM38370.raw", result)
cal_file="C:/Mantid/trunk/Test/Data/offsets_2006_cycle064.cal"
AlignDetectors(result, result, cal_file)
DiffractionFocussing(result,result,cal_file)

banks = ""
for i in range(1,7): 
    ExtractSingleSpectrum(result, result + "_" + str(i),i-1)
    banks += result + "_" + str(i) + ","
	
banks.rstrip(",")
mtd.deleteWorkspace(result)
group = result + "_grp"
GroupWorkspaces(group, banks)
SaveNexusProcessed(group, "C:/Mantid/GEM_crash.nxs")

(In [4358]) Fixed bug with MantidPlot crash on running algorithms on groups twice when the original group is still present. Also removed reference to MantidPlot within Mantid code. Re #1218
