Device deletion fails for devices with connected objects

[exokernel]

NetBox version

v2.11.6

Python version

3.7

Steps to Reproduce

1. Create a new device (I created a Dell Application Server in the demo site)
2. Create a network interface
3. Connect the network interface to a switch interface
4. Delete the device via the UI

Expected Behavior

The device is deleted and no longer shows up in search results

Observed Behavior

The device remains even after deletion apparently succeeded with no errors. It will show up in search results still and is still connected to switchport.
