Apollo link subscription never stops => Can't perform a React state update on an unmounted component

[Torsten85]

Currently the subscription inside ApolloLink does not stop on unmounting a React Component or unsubscribing to a "watchQuery" subscription. (see #6985 for a more detailed explanation whats happening)

This also results in the warning Can't perform a React state update on an unmounted component.

Intended outcome:

The QueryManager should stop the subscription from ApolloLink

Actual outcome:

Subscription never gets stopped

How to reproduce the issue:

https://codesandbox.io/s/apollo-client-321-state-unmounted-7mhi8

Versions

@apollo/client: ^3.2.1 => 3.2.1

Hey @Torsten85! Thanks for the reproduction! Can you try this with the latest version (as of now its 3.7.1)? Using your codesandbox reproduction, I was able to update to the latest client version and no longer saw this issue.

Seeing as it seems to be working with the latest version, I'm going to go ahead and close this issue as I'm also trying to do a bit of housekeeping. If you have further questions or are still seeing issues after updating, please open this issue back up and we'd be happy to help!
