logs from engine and host

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


How reproducible:
Reproduces always during execution of https://polarion.engineering.redhat.com/polarion/redirect/project/RHEVM3/workitem?id=RHEVM-18216

Steps to Reproduce:
1. Create a VM with a disk and lease (NFS in my case, disk and lease on the same domain)
2. Start the VM
3. Power off the VM
4. Create a template from the VM with a disk on the same domain as the VM disk and lease

Actual results:
Template creation fails with the following exception in engine.log:

Create template task is not cleared, hence, the VM cannot be removed without ovirt-engine restart


Workaround:
Restart ovirt-engine in order to remove the VM

Expected results:
Template creation from HA VM with lease should succceed
