test: temporary disable VirtualMachineOperationRestore (#2324)

Description
Temporarily skip VirtualMachineOperationRestore on sds-replicated-volume.

Why do we need it, and what problem does it solve?
The test is currently unstable on the existing replicated storage implementation because of snapshot-related issues. We are waiting for the new replicated implementation, so the test is skipped for this storage class for now.
