Keep GraphQL subscriptions active only on a single tab in Web

[SleepySquash]

Background

Remote updates are being received via GraphQL subscriptions.

Problem to solve

Each new instance of application opens the same subscriptions over and over again, even if those instances all share the same database, which just spams the backend and it isn't good.

Possible solutions

Since drift supports real-time local changes subscription propagating, this renders having to open multiple GraphQL subscriptions useless: one tab may connect to the updates and the other ones can just get those updates via drift subscriptions.

Roadmap:

• chatEvents subscription (Refactor RxChat.mesages pagination to watch() changes from drift #1060)
• Every other subscription (Keep GraphQL subscriptions active only on a single tab in Web (#1047) #1055)
