Description

Pascal found a difference when running 

LoadEventNexus(Filename=r'/archive/ndxwish/Instrument/data/cycle_11_3/WISH00019301.nxs',OutputWorkspace='19301full',LoadMonitors='1',MonitorsAsEvents='1')

Rebin(InputWorkspace='19301full_monitors',OutputWorkspace='19301-full_monitors_rebin',Params='5000,-0.00063,105000')
ExtractSingleSpectrum(InputWorkspace='19301-full_monitors_rebin',OutputWorkspace='19301-full_monitors_rebin_extract',WorkspaceIndex='3')

ExtractSingleSpectrum(InputWorkspace='19301full_monitors',OutputWorkspace='19301-full_extract',WorkspaceIndex='3')
Rebin(InputWorkspace='19301-full_extract',OutputWorkspace='19301-full_extract_rebin',Params='5000,-0.00063,105000')

The reason being that ExtractSingleSpectrum is not event aware and the workspace is converted to a Workspace2D and then rebinned.

Pascal needs this for the WISH scripts. Extract does not currently use CropWorkspace which I think it should.

Fixes #4001. Make ExtractSingleSpectrum event aware by making it use CropWorkspace.

Running on an event workspace gives an event workspace out and doing a script like the one above gives identical outputs.
