I'm sorry, I don't quite understand what you're trying to say. I don't
have those lines in my .emacs, and I am using the latest Evil. My
problem is that undo-tree is loaded, but disabled when I open a file
with an unrecognized extension (e.g., a file named "foo",
but not "foo.txt").

Again, the strange thing is that undo-tree is enabled on the *Messages*
buffer, but disabled (turned off) in the "foo" buffer.
