tracker issue : CF-4126619

cfpdf's action="import" incorrectly overwrites some metadata

Steps to reproduce:

1) Run below code

2) Compare CFDocumentMetadataBefore.xmp and CFDocumentMetadataAfter.xmp
2a) See pdf:Producer changed from "iText 2.1.0 (by lowagie.com)" to "Acrobat Web Capture 9.0" (bug b/c pdf:Producer is the PDF's producer and never to be overwritten)
2b) See xmp:CreateDate changed (bug b/c xmp:CreateDate is the date the resource was created and never to be overwritten)
2c) See xmpMM:DocumentID changed from undefined to defined (bug b/c xmpMM:DocumentID is only created once per resource and never to be overwritten)

3) Compare CFHTMLToPDFMetadataBefore.xmp and CFHTMLToPDFMetadataAfter.xmp
3a) See pdf:Producer changed from "Acrobat Web Capture 9.0" to "iText 2.1.0 (by lowagie.com)" (bug b/c pdf:Producer is the PDF's producer and never to be overwritten)
3b) See xmp:CreateDate changed (bug b/c xmp:CreateDate is the date the resource was created and never to be overwritten)
3c) See xmpMM:DocumentID changed (bug b/c xmpMM:DocumentID is only created once per resource and never to be overwritten)

<cfscript>
  //export metadata from cfdocument PDF
  cfdocument(format="pdf", filename=expandPath('./CFDocumentBefore.pdf'), overwrite="true") {writeOutput("my PDF");};
  cfpdf(action="export", type="metadata", source=expandPath('./CFDocumentBefore.pdf'), exportto=expandPath('./CFDocumentMetadataBefore.xmp'), overwrite="true");
  
  sleep(2000);//ensure timestamps change
  
  //export metadata from cfhtmltopdf PDF
  cfhtmltopdf(destination=expandPath('./CFHTMLToPDFBefore.pdf'), overwrite="true") {writeOutput("my PDF");};
  cfpdf(action="export", type="metadata", source=expandPath('./CFHTMLToPDFBefore.pdf'), exportto=expandPath('./CFHTMLToPDFMetadataBefore.xmp'), overwrite="true");
  
  sleep(2000);//ensure timestamps change
  
  //import cfhtmltopdf metadata into cfdocument PDF
  cfpdf(action="import", type="metadata", source=expandPath('./CFDocumentBefore.pdf'), destination=expandPath('./CFDocumentAfter.pdf'), importfrom=expandPath('./CFHTMLToPDFMetadataBefore.xmp'), overwrite=true);
  
  sleep(2000);//ensure timestamps change
  
  //import cfdocument metadata into cfhtmltopdf PDF
  cfpdf(action="import", type="metadata", source=expandPath('./CFHTMLToPDFBefore.pdf'), destination=expandPath('./CFHTMLToPDFAfter.pdf'), importfrom=expandPath('./CFDocumentMetadataBefore.xmp'), overwrite=true);
  
  //export metadata from updated cfdocument PDF
  cfpdf(action="export", type="metadata", source=expandPath('./CFDocumentAfter.pdf'), exportto=expandPath('./CFDocumentMetadataAfter.xmp'), overwrite="true");
  
  sleep(2000);//ensure timestamps change
  
  //export metadata from updated cfhtmltopdf PDF
  cfpdf(action="export", type="metadata", source=expandPath('./CFHTMLToPDFAfter.pdf'), exportto=expandPath('./CFHTMLToPDFMetadataAfter.xmp'), overwrite="true");
</cfscript>
