Description of problem:
In case of VM import of the same VM, using the same target VM name, 
the VM event, in the UI, linked from clicking the VM import "Status",
show also the events for this VM from current VM import, 
as well as the event of the previous VM import.

For example, consider this flow:
1. VM import fails. The VM events related to this VM import are listed in the UI.
2. Remove this failed VM import.
3. Fixing the problem.
3. VM import of the same VM with same target VM name.
The VM events will list the event for the current VM import, as well as the events of the previous VM import - and this second should not be displayed.

Seems the VM events are displayed by VM name, but should be also filtered as related to the current VM import.
