C++ engines bug when no updates

Describe the bug Any of the C++ engines through an error during data transformation of R objects to plain arrays due to the absences of updates on the network statistics.

To Reproduce

# # observed relational events
eventsMM <- data.frame(
  time = cumsum(
    c(1, 5, 3, 4, 2)),
  sender = sprintf(
    "Actor %d", 
    c(1, 3, 2, 2, 5)),
  receiver = sprintf(
    "Actor %d", 
    c(2, 2, 3, 3, 1)),
  increment =
    c(1, 2, 1, 1, 1),
  stringsAsFactors = FALSE
)
# # actors attributes
actorsMM <- data.frame(
  label = sprintf("Actor %d", 1:5),
  present = rep(TRUE, 5),
  attr1 = c(9.9, 0.1, 0.5, 0.45, 0.25),
  stringsAsFactors = FALSE
)

# # state at the beginning of the network
networkMM <- matrix(
  c(0, 3, 0, 0, 0,
    3, 0, 1, 1, 0,
    0, 1, 0, 1, 0,
    0, 1, 1, 0, 0,
    0, 0, 0, 0, 0), 
  nrow = 5, ncol = 5, byrow = TRUE,
  dimnames = list(sprintf("Actor %d", 1:5),
                  sprintf("Actor %d", 1:5))
)
# defining objects
networkMM <- defineNetwork(
  matrix = networkMM, nodes = actorsMM,
  directed = FALSE)
networkMM <- linkEvents(
  x = networkMM,
  changeEvent = eventsMM,
  nodes = actorsMM)
depNetMM <- defineDependentEvents(
  events = eventsMM,
  nodes = actorsMM,
  defaultNetwork = networkMM)
# model
mod01 <- estimate(depNetMM ~ inertia + trans,
                  model = "DyNAM", subModel = "choice_coordination",
                  estimationInit = list(engine = "default_c"))
