Modelling: Visual duplication in EditAppRole

[SolidProgramming]

Following on the changes in #3179 the appservers on the right side in EditAppRole popup will VISUALLY duplicate after clicking the save button. This only happens when there are appservers that are added and not when saving after making no changes think.

This could be the same problem like the one in #2692

Sorry, but I am unable to reproduce this issue on develop. I forced a slow, step by step sequence of the method Close() and the behavior I see is that the collection gets sorted (in a strange way, I admit) before closing. Is it possible, that you confused this behavior for the one you described above? Otherwise it seems to be a local problem on the machine where you tested it.
