Taking an assessment as TA when in student view can lead to misleading statistics

Description

See more details in SAM-744 reported by Stephen Marquard

This seems to have caused a regression in one unusual case where we have, where the realm permissions were changed to allow the Tutor role (equiv. to TA) to take and submit assessments. Only TAs took the assessment.

Attempting to export the results causes an error (local ref is VULA-741):

caused by: java.lang.RuntimeException: failed to call histogramScores.
at org.sakaiproject.tool.assessment.ui.listener.evaluation.HistogramListener.getDetailedStatisticsSpreadsheetData(HistogramListener.java:1934)
at org.sakaiproject.tool.assessment.ui.bean.evaluation.ExportResponsesBean.getSpreadsheetData(ExportResponsesBean.java:181)
at org.sakaiproject.tool.assessment.ui.bean.evaluation.ExportResponsesBean.exportExcel(ExportResponsesBean.java:174)

The problem appears to be in HistogramListener.java

This is somewhat an unusual case. I'm lowering it to major.
