Fix sub-resource storing the wrong index in cache

The subindex within Resource wasn't synchronized with the path stored
in cache when saving a packed scene. It could cause sub-resources to be
swapped when loading the same packed scene in the same session.

Now the subindex in Resource reflects the sub-resource path in cache,
making saving and loading sub-resources consistent.
