fixes #39

"Exceeded event list..." message was only displayed in log output.
Uncommented portion of report.xsl so that the message gets
displayed in the email report.
additional fix for #39

The message regarding multiple values being found for a field
need not be displayed in the email report or as a warning. So its
level has been changed to debug and it has been removed from the
email report.
Refactor TestCopyDataToPersonFormEventTree.py

TestCopyDataToPersonFormEventTree.py had some whitespace issues (mixing
tabs with spaces). I also removed the import hack as we now know better
python practices.
Add test showing formImportedFieldName is required

It's *supposed* to be optional, but formImportedFieldName is treated in
the code as required. This is probably because for the Pilot Project,
all our forms have imported fields.
Remove implied assert of a formImportedFieldName
