doc.UpdateTableOfContents() exception with overlap textboxes

[mike.woolsoncroft]

When template file contains overlapping textboxes and one of them is a heading, doc.UpdateTableOfContents() generates an exception:
System.ArgumentException: An item with the same key has already been added. Key: Spire.Doc.Documents.Paragraph
