Previously the `once_per_instance` used the output of `__repr__` to identify the class of where the decorated method was called from. For classes that override this method to produce the same output for different instances of the same class this caused different instances to be mistakenly treated as one. Now use the hash of the containing class instead of the string representation and update the tests to catch this error.
