Bug in ApplyTemplate fixed - document.xml.rels was written incorrectly.

DocX/DocX.cs

           finally
           {
             this.package.Flush();
+            var documentRelsPart = this.package.GetPart(new Uri("/word/_rels/document.xml.rels", UriKind.Relative));
+            using (TextReader tr = new StreamReader(documentRelsPart.GetStream(FileMode.Open, FileAccess.Read)))
+            {
+              tr.Read();
+            }
             templatePackage.Close();
           }
         }
