add more tests for findGraphQLTags, fix cache/schema tests

[acao]

another boring incremental improvement PR 😆

• re-enable some tests for GraphQLCache that were disabled after an update to graphql-config after I found a proper mocking workaround
• add more tests for cases in findGraphQLTags.ts as a follow up to feat: add gql call expressions support #2509
