Only add commands if scaffold is already loaded.

With the new hooks introduced in wp-cli/wp-cli@7fcee0e , we can now only load the commands if the parent they depend on has already been added.

This is needed because of the added flexibility provided by the bootstrap refactoring.

See wp-cli/wp-cli#3872
