Steps to Reproduce

1. Create a device with a module bay
2. Create a module type with an interface
3. Create a module of that type in the device
4. Delete the module
5. Inspect the changelog

Expected Behavior

The changelog entries should be ordered as follows (beginning from step 3 above):

1. Create the module
2. Create an interface on the module
3. Delete the interface
4. Delete the module

Observed Behavior

The changelog entries appear as:

1. Create the module
2. Create an interface on the module
3. Delete the module
4. Update the interface (appears to be a no-op?)
5. Delete the interface

Although the result of the deletion is as expected (both the module and its interface have been removed), the changelog does not accurately reflect the order of operations: In reality, any components of the module are and must be deleted from the database prior to the deletion of the module itself to satisfy foreign key constraints.

It should be noted that similar patterns likely exist elsewhere in the application, where a cascading deletion of dependent objects is not accurately recorded in the changelog. The resolution of this bug should include an audit for all such instances.
