tolerance passed to check_roundtrip

0.9

check_roundtrip() gives nice error

Code
  wrapper(NULL, list(), label = "foo", style = "json")
Condition
  Error in `wrapper()`:
  ! `foo` could not be safely serialized with `style = "json"`.
    Serializing then deserializing the object returned something new:

  `original` is NULL
  `new` is a list

  i You may need to try a different `style`.
