zeroconf: remove leftover camelcase identifier
eb9d0e828c30 (zeroconf: remove camelcase in identifiers, 2016-03-01)
forgot one occurrence of "numAuthorities", which makes test-paths.t
fail for me. I don't even know what zeroconf is, but this patch seems
obviously correct and it fixes the failing test case.
