This is supposed to be read-only, so that tools can rely on it
and to the operations they need to perform right away.

Raw Devfile objects can still be obtained upon request
if there is need to update them (for example via 'odo add/remove
binding' commands.

… effective view

- The test spec was actually not doing what it was supposed to do
- Now 'odo init' returns a complete Devfile, where the parent is flattened,
  because the goal of 'odo init' is to bootstrap a Devfile.
  Previously, 'odo init' would not download the parent referenced,
  making it hard to understand the resulting Devfile.

This would change the behavior of `odo init`.

Furthermore, due to an issue [1] in the Devfile library,
it is not possible to parse some Devfiles with parents linked as GitHub URLs (like GitHub release artifacts).
