userVmResponse no longer returns some parameters

[Alena Prokharchyk]

Hi Daan,

In the latest master build I observed that listVirtualMachines command no 
longer returns parameters like:

State
displayName
Account

Its due to the commit that you’ve cherry-picked 
(fae05560218ef3bcb962bd424ae5dbf5cb8ede68)

Setting corresponding fields in UserVmJoinVO to become final, causing them to 
always return NULL in the response.

Can you please fix it? Current behavior will break all integration code.

Thanks,
Alena.
