Description of problem:
If VMware to OSP migration is failed, volume that was created during migration process fails to clean up if the volume has been detached from conversion host and moved to different project where the migrated VM was supposed to be. 


Version-Release number of selected component (if applicable):
CFME 5.10.0.24

How reproducible:
Believe 100%

Steps to Reproduce:
1.Configure OpenStack Conversion Appliance Instance
2.Add OpenStack and VMware to CFME 
3.Create infra mapping and migration plan
4.Execute migration plan, wait for completion, we would ideally want it to fail so we can see the cleanup phase taking place.

Actual results:
Failed migration leaves stale volumes that are not attached to anything. 

In the traceback given below, I was migrating VM to "qe_destination_1" project and conversion host was under "migration" project. When Migration was almost finishing, volume related to migrated VM was detached from conversion host and moved to "qe_destination_1" project. Migration failed to create network port so it tried cleaning up the volume in "migration" project which was no longer present in that project as it was already transferred. 

Expected results:
Virt-v2v-wrapper should know how to clean up the volume even if it has been moved to different project than the one where we have conversion appliance.
