Use epub output to trigger downloadOrRead in Text.Pandoc.Class in order to test file: URL-scheme handling.

There are no relative file: URLs, so we cannot test with an actual file, since we don't know the current working directory. Instead, we use /dev/null as a file that certainly exists, redirect stderr to stdout and check that there is no warning.
