CalculateEfficiency uses from pixel identifier

[Mathieu Doucet]

CalculateEfficiency should be using WorkspaceIndexList rather than SpectraList when using MaskDetectors.

Note that this does not affect HFIR SANS because the workspace index and the spectrum index are the same for those geometries.

To test: check that the affected line of code has been changed and that the systems tests still run.
