Conveyor placement near devices is sketchy

[katepolak]

Describe the bug
Under the correct circumstances, which is when there is a 1 block wide gap between a conveyor and a device, when you try to place that one missing conveyor it freaks out connecting to non existing places, the behavior changes depending on what part of the voxel underneath you point at.

Probably related to #10.
