While testing the previous commit, it became clear that gourd stems do not disconnect properly if the gourd disappears while not being dug. A simple method to create illegal curved stems was to explode the gourd. This patch changes gourds so that the stem curves back after a gourd is destroyed, regardless of reason. This hopefully makes curved stems that are not connected to matching gourds a relict of the past.
