* Fix bundle path to make spec tests work
On iOS, resources are directly within the bundle so the bundlePath and
the resourcePath are the same.
On macOS, resources are in a Contents/Resources subfolder so enumerating
from bundlePath causes us to look for names like
Contents/Resources/offline_spec_test, which doesn't work.
