When the compute host recovers from a failure the compute manager
destroys instances that were evacuated from the host while it was down.
However these code paths only consider evacuated instances that are
still reported by the hypervisor. This means that if the compute
host is recovered in a way that the hypervisor lost the definition
of the instances (for example the compute host was redeployed) then
the allocation of these instances will not be deleted.
This patch makes sure that the instance allocation is cleaned up
even if the driver doesn't return that instance as exists on the
hypervisor.
Note that the functional test coverage will be added on top as it needs
some refactoring that would make the bugfix non backportable.

cleanup evacuated instances not on hypervisor
