test/scenarios: Mark docs as up-to-date in init()

  Files and directories created during the scenarios init phase are
  supposed to be synchronized with the Cozy.
  Since we rely on both sides to be 2 after the first synchronization,
  we should mark them as such in `test/support/helpers/scenarios.js`
  when creating them in the `init()` function.

  The double `pouch.put()` calls are meant to increase the document's
  `_rev` until it's in sync with its sides.
