Remove oddly named sample file.

With a fresh checkout on my Mac, git reports an untracked file:
Products/feedfeeder/tests/samples/te\314\200st4.odt
When I remove *.odt, git reports that this file is missing:
Products/feedfeeder/tests/samples/t\303\250st4.odt
Weird.
I remove the file and then add it again and see if this solves it.
Add Products/feedfeeder/tests/samples/te\314\200st4.odt again.
