Netbox: Missing info on circuits terminations points

[zacho112]

• Python version: 3.6
• NetBox version: 2.8.4

Steps to Reproduce

1. Add a new circuit
2. Add a termination point A (Add site + speed)
3. Add a termination point Z (Add site + speed)
4. Add a connection on termination point Z, select destination device + interface

Expected Behavior

The interface on the device shows connection to the Circuit and vise versa.

Observed Behavior

Both the interface and the termination point only shows connection to the cable, not the device/interface

This happened after a recent update from 2.7.7.

If I delete the termination point A, and edit the cable the missing info shows up.

Exact same issue on upgrade from 2.7.10 => 2.8.5.

We observed a similar behavior when creating new circuits with both A/Z side connected to a device interface. (Existing circuits are fine)

Creating a new circuit with only A side connected to a device interface works okay.

As soon as Z side is connected infos are missing in the circuit view for Z side.
Also circuit termination isn't displayed on the device view (both sides), it's show that devices are directly connected (which is not the case).

The same issue when 2.7.12 => 2.8.5.

I guess its the same issue as in https://github.com/netbox-community/netbox/issues/4619
