split_tab = TRUE in tab_multi_manager is not working well

[julienjamme]

To reproduce the error :

library(rtauargus)
loc_tauargus <- "Y:/Logiciels/TauArgus/TauArgus4.2.3/TauArgus.exe"
options(rtauargus.tauargus_exe = loc_tauargus)

data("datatest1")
data("datatest2")

res <- tab_multi_manager(
  list_tables = list(d1 = datatest1, d2 = datatest2),
    list_explanatory_vars = list(
        d1 = names(datatest1)[1:4],
        d2 = names(datatest2)[1:5]
    ),
 dir_name = "tauargus_files",
 value = "pizzas_tot_abs",
 freq = "nb_obs_rnd",
 secret_var = "is_secret_prim",
 totcode =  "Total",
 split_tab = TRUE
)

During the process of tab_multi_manager, it's important that the "primary secret" variable at each step is moving from one iteration to the following one.
