Rename default import from mock_apollo_helpers

- in mock_apollo_helpers, the default export is usually named
  createMockApollo
- then a utility method called `createMockApolloProvider` is
  created to utilize createMockApollo
- naming the imported method `createMockApolloProvider` could be
  confusing, so I am renaming it
