wp-now: Running a blueprint with no steps prop fails

[senadir]

on @wp-now/wp-now:0.1.72, running something like this blueprint would fail

{
  "$schema": "https://playground.wordpress.net/blueprint-schema.json",
  "landingPage": "/wp-admin/post-new.php",
  "preferredVersions": {
    "php": "latest",
    "wp": "latest"
  },
  "phpExtensionBundles": ["kitchen-sink"],
  "plugins": ["gutenberg", "woocommerce"],
  "features": {
    "networking": true
  },
  "login": true
}

Error:

TypeError: blueprintObject.steps is not iterable
    at extractSiteUrlFromBlueprint (MY_FOLDER/node_modules/@wp-now/wp-now/main.js:566:38)
    at getWpNowConfig (MY_FOLDER/node_modules/@wp-now/wp-now/main.js:554:21)
    at async Object.handler (MY_FOLDER/node_modules/@wp-now/wp-now/main.js:1098:25)

You can fix it by adding an empty "steps": [] prop to the blueprint.
