fetchPolicy no-cache not working

Describe the bug
The fetchPolicy 'no-cache'is supposed to disable the default behavior for GraphQL queries to take the cached response of the query and thus save on network requests. I always wanted this behavior but never got it working in my app. Now I have set up a fresh project just for demo and it is not working here either.

To Reproduce
Steps to reproduce the behavior:

Try to send the same graphql query two or more times and notice it will only send one network request.

I have setup a demo project for this: https://github.com/mg98/apollo-cache-not-working
I created it with the Vue CLI and vue add apollo with pre setup configuration. Follow the readme to start the app. There will be a text explaining you how to test the behavior.

Expected behavior
Always send a network request, because I globally set fetchPolicy to 'no-cache'.

Versions
vue: 2.6.11
vue-apollo: 3.0.0.beta.11, I can also verify for 3.0.3

Start with the linked reproduction project's README and follow its steps to run the Vue CLI demo. Trace how vue-apollo 3.0.x applies the global fetchPolicy setting, then repeat the same GraphQL query and verify that no-cache produces a network request each time.
