--exclude flag does not accept an array as expected

[Genkilabs]

Per the docs, adding a space-delimited list of strings to the --exclude flag seems to cause the last parameter, the host, to be gobbled by the array. Singly the --exclude seems to work.

I tested this against a new Rails server with nothing in the routes except failure statuses expecting to be able to isolate specific routes as I implemented them. For example:

# GET /resources/:id/measures
def measures
	render :json => {:message => "Not yet implemented"}, :status => :not_implemented
end

Single param working example:

grafton test --product=bonnets --plan=small --region=aws::us-east-1 \
    --client-id=21jtaatqj8y5t0kctb2ejr6jev5w8 \
    --client-secret=3yTKSiJ6f5V5Bq-kWF0hmdrEUep3m3HKPTcPX7CdBZw \
    --connector-port=3001 \
    --new-plan=large \
    --exclude plan-change sso \
    http://localhost:3000

The above works great!

However if you add additional exclusions the host is lost

> grafton test --product=bonnets --plan=small --region=aws::us-east-1 \
     --client-id=21jtaatqj8y5t0kctb2ejr6jev5w8 \
     --client-secret=3yTKSiJ6f5V5Bq-kWF0hmdrEUep3m3HKPTcPX7CdBZw \
     --connector-port=3001 \
     --new-plan=large \
     --exclude plan-change sso \
     http://localhost:3000

cleanup: Remove dangling resource due to failed provision
  Default case
    Expected a successful provision of a resource
    http: no Host in request URL
  Default case ✗
provision: Provision a resource
  Default case
    Expected a successful provision of a resource
    http: no Host in request URL
  Default case ✗

For my two cents, I would prefer an --only flag or something so that I could run the test one by one down the list and cut out the noise during initial development.
