Regression: Client crashing when updating CachedChatSubscription

[gabriellsh]

Proposed changes (including videos or screenshots)

Currently the typing of 'ISubscription' is a little off from reality. The property ts is optional, and this can cause crashes when trying to access ts's properties.

I decided to avoid changing the type definitions for ISubscription this time, since it will probably impact many other places, and that's not the scope of this task.

Issue(s)

Steps to test or reproduce
