Add checks for invalid trace data in removeDuplicateTraces
Add checks for invalid trace data in removeDuplicateTraces

This change addresses defect SW457275 where hbrt was crashing
while removing duplicate traces in an error log that had
corrupt trace meta data. The corrupt meta data was causing
code to write to an invalid memory location.  This change
adds some checking of the meta data and traces some debug
data that might be useful in debugging future cases of
corrupt meta data.
