Removing reverselist() from all bot pathing.

As with my previous commit, reverselist() is causing problems in bot
pathing, it is unnecessary. Bot pathing only worked when reverselist()
was doing nothing.

Similar to https://github.com/Baystation12/Baystation12/commit/823021483353cdfcc83538522a01975ff773042a
and 
https://github.com/tgstation/-tg-station/commit/54d02d75a3da4ae3a73e00eea34d4bbfa3d6e73f

These problems are only noticeable with more complicated paths where reversing the order matters, i.e. not straight lines.
