AttributeError raised when deleting a CircuitTermination with attached cable -> interface

[kkthxbye-code]

NetBox version

v3.4.2

Python version

3.10

Steps to Reproduce

1. Create a Site testsite
2. Create a manufacturer testmanu
3. Create a device role testrole
4. Create a device type testdevicetype
5. Create a device testdevice with the above pre-requisites
6. Create two interfaces inf[1-2] of any physical type
7. Create a Provider testprovider
8. Create a CircuitType testcircuittype
9. Create a Circuit testcircuit wit the above requisites
10. Create two CircuitTermination (A & Z) to site testsite on the circuit
11. Connect end A to inf1
12. Connect end Z to inf2
13. Press the delete button next to the swap button on CircuitTermination A
14. Press delete

Expected Behavior

Circuit termination is deleted

Observed Behavior

The following exception is thrown:
