fixed misleading test

this was forgotten in 8d4db7e

note that this reveals an inconsistency within faucet-core WRT how
module paths are handled between Node versions: legacy mode (Node v6)
does not fall back to relative paths while non-legacy mode (Node v8)
does attempt to use relative paths if no corresponding package path
exists
