Try fixing ThreadResolveWorker calls (#3599)
* Try fixing ThreadResolveWorker calls

From my understanding of ActiveRecord, a transaction is commited as soon as
the exit of the outmost ActiveRecord.transaction block. However, inner
transaction blocks will exit without the transaction being commited.

In this case, ThreadResolveWorker were fired *within* a transaction block,
so moving the call out of it should do the trick. However, this is somewhat
fragile, as this whole codepath could be called within yet another transaction.

* Set status thread within the transaction block if it is immediately available from database
