Reference tracking reports nonsensical values

[DamianX]

I added reference tracking to /vg/station with vgstation-coders/vgstation13#26900 .

There are a few issues:

• Accessing the "type" var of some of the references returned by extools sometimes causes a runtime error.
• Some references are reportedly from variables that don't exist on the specified type, like here: [0x21024d6e] | /datum/delay_controller | speaker delay_controller has no var named speaker.

Think it's an issue with DelDatum not necessarily always being called when a datum is deleted. It might be just called 95% of time and when you get these nonexistent vars it might be a case of a recycled ref. Will look into it later
