Batch cloning doesn't clone individual lifetime data

[Enchufa2]

From #264, nested clones seem to work just fine; the issue instead has to do with batch cloning:

library(simmer)

t <- trajectory() %>%
  log_("started") %>%
  batch(3) %>%
  clone(n = 2,
        trajectory() %>%
          timeout(4),
        trajectory() %>%
          timeout(5)) %>%
  synchronize(wait = TRUE) %>%
  separate()

simmer() %>%
  add_generator("dummy" , t, at(c(5, 10, 20))) %>%
  run() %>%
  get_mon_arrivals()
#> 5: dummy0: started
#> 10: dummy1: started
#> 20: dummy2: started
#>     name start_time end_time activity_time finished replication
#> 1 dummy0         25       25             5     TRUE           1
#> 2 dummy1         25       25             5     TRUE           1
#> 3 dummy2         25       25             5     TRUE           1
