Create a data.frame representation from remote users.

[jonkeane]

We need to do slightly more than simply making a data.frame from the results:

remote_users <- client$users_remote(user_prefix)
tibble(
  username = map_chr(remote_users$results, ~.$username),
  fist_name = map_chr(remote_users$results, ~.$first_name),
  last_name = map_chr(remote_users$results, ~.$last_name),
  guid = map_chr(remote_users$results,  ~ifelse(is.null(.$guid), NA, .$guid)),
  temp_ticket = map_chr(remote_users$results, ~.$temp_ticket)
)
