Description of problem:

I imported a vm and restarted vdsm during the import. 
After we reselected an SPM I tried to import the same vm again and failed with error from vdsm:

How reproducible:

100%

Steps to Reproduce:
1. create a vm from template and export both vm and template
2. remove the vm and template from the export domain
3. import the vm with collapse and restart vdsm during the import
4. after we select a different spm try to import the vm again. 
  
Actual results:

we fail to import the vm with error in vdsm:

Expected results:
