tests: Fix verifier '_iterable_regex' func for None regex

In the case where no regex was specified (i,e., `regex == None`), the
`_iterable_regex` function returned `None`. For the testlib to work this
function must return an iterable.

Without this patch it is not possible to compare two files without a
specifying a regex.
