[V1.59 (Stable) - Geoscape] Rapid Fire Plasma research auto completes base defense

If you have base defense laser battery under construction and you complete Rapid Fire Plasma research, then the base defense battery will skip the construction time and automatically be completed ready for use.

I suspect that the auto upgrade that happens to base defense turrets upon completion of the appropriate research topic does not check for the base defense battery construction days status and just overwrites the defense battery data with the fully completed upgraded defense battery data.

This bug could be exploited to setup base defense turrets without having to wait for the 10 day construction time. Research the appropriate Rapid Fire Laser or Plasma research up to near completion then remove all scientists working on the project. Then whenever the player needs base defenses setup very quickly they can start the Defense Battery construction and then assign scientists to complete the already nearly complete research topic which when completed will now insta-construct the under construction Base Defense Battery skipping the 10 day construction time.

I also suspect that other base facilities that can be upgraded could also be exploited in this manner to skip construction times.
