Fix Research Disposal Pipe (#4307)

# About the pull request

Fixes a broken pipe in research that resulted in any items placed in the
disposal bin in the frontal chemical area being dumped in the disposal
bin in the main research room instead of being sent to the trash room.

# Explain why it's good for the game

While its very funny to see a hundred pills strew all around research,
its clearly not intentional.
