Pathname#exist? does not seem to be wrapped

[dkubb]

I was using Pathname#exist? within some code, and noticed it was not being wrapped by fakefs. It looks like Pathname uses FileTest, rather than File (no idea why). I worked around it with a monkey patch:

# fakefs does not wrap FileTest methods, which Pathname delegates to
class Pathname
  def exist?
    File.exist?(self)
  end
end

Add FileTest#exist? Swap out FileTest for FakeFS::FileTest. Closed by 50193f2
