unhandled promise rejection on Before and After sections

[robinComa]

Hello,

Requests on the before and after section have unhandled promise rejection. When the request is in timeout for exemple the subprocess don't stop correclty.

Here an exemple :

config:
  ...
  http:
    timeout: 10
 ...
before:
  beforeScenario: "useDate"
  flow:
    - log: "* GET /api/auth/login"
    - post:
        url: "/api/auth/login"
        json:
          login: "{{login}}"
          password: "{{password}}"
        capture:
          - json: $.token
            as: "token"
    - log: "Bearer token : {{token}}"
after:
  flow:
    - log: "* DELETE /api/auth/logout"
    - delete:
        url: "/api/auth/logout"
scenarios:
  - flow:
    - get:
        url: "/"
        headers:
          authorization: "Bearer {{ token }}"
        expect:
          - statusCode: 200

Sometimes the login or logout is in timeout (or something wrong, status >= 400) and the process stop with this log :

* DELETE /api/auth/logout

(node:761) UnhandledPromiseRejectionWarning: Unhandled promise rejection. This error originated either by throwing inside of an async function without a catch block, or by rejecting a promise which was not handled with .catch(). To terminate the node process on unhandled promise rejection, use the CLI flag `--unhandled-rejections=strict` (see https://nodejs.org/api/cli.html#cli_unhandled_rejections_mode). (rejection id: 1)
(node:761) [DEP0018] DeprecationWarning: Unhandled promise rejections are deprecated. In the future, promise rejections that are not handled will terminate the Node.js process with a non-zero exit code.

All process is stopped, and artillery don't run anymore.
