BCI implanters no longer drop their BCI on the floor when opened (#63204)

Exactly what it says in the title. Implanters used to drop the BCI they contained when opened up. Now they don't. For good measure I made them drop their contained BCIs when deconstructed as well in case they already did that as a consequence of the BCI being located inside the implanter, which was the cause of the issue in the first place.
