fix(core-tester-cli): Don't hide errors from HTTP failures (#2223)

Before this patch we would just get the following error, leaving one to
wonder what went wrong:

  [1552298227459] ERROR (core-tester-cli/40747 on smle): Cannot destructure property `data` of 'undefined' or 'null'.

After this patch:

  [1552299329734] ERROR (core-tester-cli/3408 on smle): http://localhost:4003/api/v2/node/configuration: connect ECONNREFUSED 127.0.0.1:4003
  [1552299329735] ERROR (core-tester-cli/3408 on smle): Cannot destructure property `data` of 'undefined' or 'null'.
