Live migration of Domains results in a blank name

When live migrating a domain between two hosts using the domain.migrate(), domain.migrate2(), domain.migrate_to_uri(), or domain.migrate_to_uri2() functions, the domain's name gets changed to a blank string.

This can cause many issues, such as being unable to perform actions on a stopped domain through virsh (as virsh commands won't accept a blank string as an argument), or being unable to have multiple live-migrated domains on as single host (because you can't have multiple domains on a host with the same name and renaming the domain requires it to be stopped).
