Apollo Client 2.5.0 and apollo-link-state

[frandiox]

Apollo Client 2.5.0 bundles apollo-link-state already so this dependency could be removed from this package.

Looks like there are some minor breaking changes as well:
Found @client directives in query but no client resolvers were specified. You can now pass apollo-link-state resolvers to the ApolloClient constructor. This happens in new installations of this plugin since it requires ^2.4.

A quick workaround for this is pinning apollo-client version (with Yarn in this case):

  "resolutions": {
    "apollo-client": "2.4.13"
  }
