Turtle shapes that contain a space (e.g., "circle 2") ruin the simulation results tibble

[aosavi]

I request the shape of a turtle in the metrics.turtles object, e.g.,

metrics.turtles <- list("turtles" = c("who", "shape"))

One of the shapes is "circle 2", but when creating the results tibble with nlrx::run_nl_all(nl), these are considered two separate character strings, "circle" and "2". This ruins the results tibble.

I assume this will also give problems for other turtle or link metrics that contain spaces.
