spec/storage: Reset build context of test stanza make comparisons easier While building a stanza there's a .last_add field keeping track of where in the XML tree tags are being added. This field does not survive a roundtrip through preserialize / deserialize. :reset() removes this, which simplifes comparisons after such a roundtrip.
