Add refetch queries to create and delete mutations.

[peterp]

We've changed to the default caching policy in Apollo's client. So now we're require to update our cache manually. This adds a stop-gap solution which reloads the queries.

We're going to evaluate different GraphQL clients, and based on the evaluation, we'll add a more robust cache updating technique or switch libraries.

@peterp Thank you! 🚀 Reviewing now, just want to pull down and run it locally.

@peterp can't get it to work locally; still seeing the same behavior. Just to confirm the steps:

• made new redwood app
• upgraded it to canary
• pulled down this branch in my local copy of this repo, yarn installed and built
• yarn rwt cp to redwood app
• generated scaffold (I see refetchQuery and awaitRefetchQueries there, so everything looks good)
• should work?

Ok! Computers are awesome, but humans are dumb. I'm sorry I type code.
