[PATCH 2/2] tests: Destroy domain object properly

[Michal Privoznik <mprivozn@xxxxxxxxxx>]

In a lot of cases we do plain virObjectUnref() with the domain
object lock held. While this looks okay, what really happens
under the hood is that we destroy a locked mutex. But with a help
from virDomainObjEndAPI() we can do the right thing and unlock
the mutex before destroying it.
