FIX: duplicate topics in digests / summaries (#29517)

Browse Source 
When using the `digest_suppress_tags` site setting to list some tags that should be removed from the digests, if there was a topic that had one suppressed tag and other regular tag(s), it would be duplicated in the summaries.

Thanks to @scossar for [figuring it out](https://meta.discourse.org/t/multiple-repeated-summary-mail-entries/296539/30).
