`Tried to activate scope outside of logging context` in `EndToEndKeyWorkerStore`

This issue has been migrated from [#12249](https://github.com/matrix-org/synapse/issues/12249).

While looking through the most frequent sentry reports, I spotted that we have seen only one scope outside of logging context error in the last 30 days:

Regrettably, synapse logs have already rotated out. But the transaction `invalidate_cache_and_stream`

is called in two places: one inside `claim_e2e_one_time_keys`

and another inside `set_e2e_fallback_keys`:
