[risin42]

Fixes a connection issue (stuck on updating/loading) caused by an upstream TLRPC refactor.

Steps to reproduce:

1. Go to Experimental settings. Notice the "disable sensitive content filtering" option is disabled.
2. Go back to the dialog list and tap to open any group or profile. You'll see it gets stuck on updating or loading.

issue: Add error handling for the case where the request fails

Currently, if the request fails (error != null), the UI state won't be updated. This could lead to inconsistent state. Consider handling the error case appropriately.
