feat: add test for UpdateKeyMaterial - WPB-17367

[KaterinaWire]

WPB-17367 [Android] unlimited MLS jobs when sync goes live

Issue

Android clients have an issue updating key material. The idea behind this PR is to add a test that covers the issue found on Android, prove that we have the correct implementation, and prevent it from breaking it in the future.

The issue was:

1. Android runs their renew key material job and finds 3 conversations requiring an update.
2. When executing 2 out of 3 re-newals succeed
3. Since one re-newal failed, the whole job also failed.
4. The timer to check every 24h will not be reseted meaning it will try again and again and again on every time the app goes live.
