(graphcache) - Fix updates config for renamed root schema types

[kitten]

Summary

When the schema contained differently named root types, e.g. root_mutation instead of just Mutation the store.updates config would be malformed and would even at times cause runtime crashes. This is now fixed by reformatting the updates config to contain the correct keys.

Set of changes

• Use actual root names in store.updates keys
• Update schema predicates to use new updates
• Simplify schema predicates calls in store.ts
