NeonWALReader needs to know LSN before which WAL is not available locally, that is, basebackup LSN. Previously it was taken from WalpropShmemState, but that's racy, as walproposer sets its there only after successfull election. Get it directly with GetRedoStartLsn. Should fix flakiness of test_ondemand_wal_download_in_replication_slot_funcs etc. ref #9201
