Fix background reindex of origin_server_ts

Browse Source 
The storage function `_get_events_txn` was removed everywhere except
from this background reindex. The function was removed due to it being
(almost) completely unused while also being large and complex.
Therefore, instead of resurrecting `_get_events_txn` we manually
reimplement the bits that are needed directly.
