Since 3.7 `successful` raises a `ValueError` as explained in the next text block from the documentation:

_Changed in version 3.7: If the result is not ready, ValueError is raised instead of AssertionError._

Should be backported in 3.7 and 3.8.

Copying property objects results in a TypeError. Steps to reproduce:

```
>>> import copy
>>> obj = property()
>>> copy.copy(obj)
````

This affects both shallow and deep copying.
My idea for a fix is to add property objects to the list of "atomic" objects in the copy module.
These already include types like functions and type objects.

I also added property objects to the unit tests test_copy_atomic and test_deepcopy_atomic. This is my first PR, and it's highly likely I've made some mistake, so please be kind :)
