Apollo Dev Tools don't refresh data

[changLiuUNSW]

I'm not able to see whats in my cache via apollo dev tools.

However I can see the cache if I run APOLLO_CLIENT.cache.data.data in the console, so the data is there.

I found a similar issue in apollo-client-devtools repo:
apollographql/apollo-client-devtools#294

The above issue is resolved in v2.3.4
apollographql/apollo-client-devtools#321

I think we need to bump up the Apollo dev tool to the latest.
