core: Fix race cond for NextRun and HA VM

The RunVm command needs to wait on the NextRun
application by ProcessDownVm.

Fixes race condition after cluster version change in
following scenario:
- old cluster, running HA VM
- cluster upgrade, so NextRun config is created
- crash of the HA VM (like kill -9 [qemu_process)]

- AutoStartVmsRunner can't be executed before ProcessDownVm finishes
