Fix 'on_*=rename-restart' domain configuration option.
When setting e.g. 'on_crash=rename-restart' option in domain config
and crashing guest OS running in the domain, the new domain is
restarted with same name as renamed domain.

This patch copies the domain info prior to setting new name and uuid
in the crashed domain info and uses the copied domain info to
construct the restarted domain.
