/diff endpoint reports no diff in redorderd lists

[rosibaj]

Description

When comparing two dictionaries with the /diff endpoint, if a list is reordered it reports an empty diff object for that field

Expected Behaviour

This should not be reported as a difference, as the data hasn't actually changed.

Actual Behaviour

Possible Fix
