fixed unexpected reflect behavior
After tls.Unmarshal() an empty slice is not assigned the nil value, but rather a slice of zero length. It is in contrast to NewTreeHeadV1(), which assigns a nil value. Therefore, reflect.DeepEqual() considers them to be different. Fixed by assigning an empty tree head extension as `make([]byte, 0)`, and not looking for nil values but rather zero-length values with len(). Further read: "Note that a non-nil empty slice and a nil slice [...] are not deeply equal." (https://golang.org/pkg/reflect/#DeepEqual).
