Duplicating a file doesn't track history with SDK style .csproj file

[michaelaird]

With the "legacy" style csproj file, AnkhSVN2019 correctly recognizes when you copy/paste the same file in the same location as copy of the original file. A new file is created called "(original) - Copy" and the SVN history is maintained.

When the project uses the new SDK style, the duplicated file is created and added to SVN but it loses the history of the original file.

AnkhSVN does quite a bit of educated guessing to follow renames as Visual Studio itself is not really interested in tracking them, nor are the SCC providers that Microsoft directly supports.
