fix aux base console (tgstation#61306)

the Auxbase console is a subtype of consoles, despite being a wallmount, therefore it inherits consoles density = TRUE, despite being on a wall

this means that you get THIS ..... its on the WALL and the tile is EMPTY, but you cant step onto it, because the consoles there technically and dense

(I feel i should clarify before its asked: when a console is deconstructed it spawns a new console frame and copies the circuit over, that new frame will be dense again. so it only lacks density once its finished and on the wall)
