Steps to Reproduce
In a scenario where stale cable paths exist, an IndexError exception may be raised. For example, this may occur when querying for /api/circuits/circuit-terminations/<id>/paths/. This is because the get_path() method on CablePathSerializer assumes that every set of nodes within path_objects will have at least one node.
(Stale cable paths should be removed automatically, preventing this scenario, but we have observed it in production.)
Expected Behavior
Invalid paths should be silently ignored.
Observed Behavior
An IndexError exception is raised.
