Module interface creation error

[mmfreitas]

NetBox version

v3.2.0-beta2

Python version

3.8

Steps to Reproduce

Reproducable in beta demo site.

1. Navigate to router dmi01-akron-rtr01;
2. Create interfaces "GigabitEthernet2/1/[0-3]" of type "1000BASE-T (1GE)";
3. Add components -> Module Bay, Create "Bay 2" with position "2";
4. Create a new Module Type -> "4PORT 1GE" and add interfaces "GigabitEthernet{module}/1/[0-3];
5. Install the created module type on the router module bay. (Replicate components must be ticked)

Expected Behavior

Observed Behavior

Since the interfaces with that name already existed, netbox throws an exception. I believe that this should be the expected behaviour but it should generate a toast error instead.

I'm going to close this bug as a duplicate of #9190, as that issue does not rely on demo data and has some conversation attached.
