The guard's regression cases only exercised renames, so dropping the
IsRenamed conjunct (failing every non-VMInstance restore) or keying the
check on targetApplicationRef.kind instead of the backup's kind left the
package green. Add the inputs the guard must let through, a VMDisk copy
that keeps its name and a VMDisk in-place restore without
targetApplicationRef, and a VMDisk backup restored with a VMInstance
target kind, which must still be rejected by the source kind.
