`delete` event does not occur for retweets of deleted tweet anymore

[SaschaNaz]

Repro:

Tweet “foo” -> tweet id 1
Retweet id 1 -> tweet id 2
Delete id 1

Previous behavior:

delete event for id 1
delete event for id 2

Current behavior:

delete event for id 1

Is this a bug or an indented behavior change? Now I have to search on every stored tweet object without any help from binary search.
