Use catalog=True for package_loader queries

Package loader attempts to load packages during deployment, therefore it
needs to see all the packages it can deploy, therefore it needs
catalog=True context for that.
This is related to api behaviour change, that allows packages api to
distinct between packages one can deploy and packages one can edit.
