I understood your problem. problem related to your roaming profile. As you noticed you are using persona management to save your profile to shared location. You have to log out every VMs and then better to recompose that all vms. after that go to your persona management profile saved location (shared location) and delete thinstall folder or any of folder inside that you unwanted.
Please make sure that you have not any vms with your previous profile the thing is when you logged back to it old profile again can sync.
Hope this will solve your problem. Please check and let me know any further details about vmware horizon environment as well as thinapp.
