vm: tests: add test for initial vcpu limit setup

We update the vm vcpu limit both on startup - if SLA QOS policy is given
and after policy updates received from clients (e.g. Engine).
We had tests for the latter, not for the former cases.

This patch adds the missing test.
For the sake of the practicality, we take one shortcut and we test
a private Vm method. This is bad, but not having tests it is even
worse, as the related BZ demonstrates.
