* fix: Remove state argument from resolvers.
State is no longer the first argument to resolvers as of @wordpress/data
version 3.0.0
* Update @wordpress/data to 3.1.0
* Adjust resolvers to work with v2 and v3 wp.data
This adds code to inspect the arguments of the resolvers to allow for
working with v2 or v3 wp.data. This is only temporary.
* resolvers: fix tests
This fixes tests by removing empty state objects from them.
