Description of problem:
After you rename VM, its events will disappear from events subtab in userportal and there is only one event saying that it was renamed.
In webadmin events don't disappear

Another problem is that if you have VMs with names for example: "old" and "another", and you rename "old" to "new" and "another" to "old", then VM which currently has name "old" sees events generated for machine that previously had name "old"

Version-Release number of selected component (if applicable):
3.2.0-11.29 (sf17.2)

How reproducible:
Always

Steps to reproduce:
1: Rename VM
2: Go to events subtab of renamed VM in userportal

Actual results:
Only events generated after renaming VM are shown (including event that says VM was renamed)

Expected results:
All events generated before renaming VM should be shown too

Additional info:
It's working correctly in webadmin
