Fix edmProvDump handling of processing history

[Dr15Jones]

Recording the processing history was not always correct for
edmProvDump. This did not affect the default print out from the
program but did affect getting additional information. Previously,
only the earliest process would get its additional information dumped
if there was only one process history associated with the file.
