Do not add dependency to parent pack if subpack is ignored dependency

[ashleywillard]

If we have a file like this for packs/fruit:
fruit.yml

dependencies:
  - packs/orange
ignored_dependencies:
  - packs/apple

and we move packs/apple under the parent packs/fruit, we get

dependencies:
  - packs/orange
  - packs/fruit/apple
ignored_dependencies:
  - packs/fruit/apple

This PR changes move_to_parent such that this is now the output:

dependencies:
  - packs/orange
ignored_dependencies:
  - packs/fruit/apple

[ashleywillard]

This had to be moved after replacing ignored dependencies so we can look for the new package name
