Proxyconnector feature is broken on SQL server repositories

[Geert Bellekens]

Creating a trace relation between an association and a class seems to be working fine, but after reloading the diagram the relation is not found.
This seems to happen only on my existing SQL Server repositories, not on a new .eapx repository.
On the same repository, with version 15.1 this is not a problem.

This is after running a project integrity check, and disabling all add-ins.

Steps to Reproduce:
- Create a diagram with three classes A, B, C and an association between A and B
- Select Trace from the toolbox and create a relation between the association and class C
- Save the diagram
- Close the diagram and reopen it
- Notice that the trace relation is gone.

Reported like this.

In the meantime I did some more experiments, and apparently is not really linked to version 15.2. I've been able to reproduce this issue in 15.1 as well.
And sometimes it also seems to work in 15.2.
If I create both the association as the trace in one go and then save diagram is seems to be saved.

If I create the association first, then save the diagram, and then create the trace, the trace is lost after reloading the diagram.

13.5 works correctly.
