Description of problem:

error message presented to user when trying to export a vm with the same name is that there is already a vm with the same id - this is wrong. 
we check both name and vm id so each error should have its own text. 

Version-Release number of selected component (if applicable):
ic145.1

How reproducible:
100%

Steps to Reproduce:
1. create a VM
2. export the VM
3. remove the VM and create a new vm by the same name 
4. try to export the vm

Actual results:

we get a CanDoAction from backend that vm id already exists. 

011-10-23 18:20:25,240 WARN  [org.ovirt.engine.core.bll.ImportVmCommand] (pool-11-thread-962) CanDoAction of action ImportVm failed. Reasons:VM_CANNOT_IMPORT_VM_EXISTS,$VmName 
NFS-02,VAR__ACTION__IMPORT,VAR__TYPE__VM

Expected results:

since the ID does not exists (it's a completely different VM with a different id) but the name does exists we should change the text of this alert.
