[2.0.28] Biolab consuming energy and producing non-zero pollution on item insert and when placed

[Agnasius]

Placing a biolab or inserting an item into it causes the lab to produce a very small but non-zero amount of pollution.
I would expect it to only produce pollution if it is active, i.e. currently researching, however, it does this even in an entirely new save with no research going on. On further inspection, I assume that this is caused by each insertion using up a small amount of the biolab's internal energy buffer, causing it to produce a little pollution in return, but it stops as soon as the internal buffer is empty. (A normal lab also loses energy on each insertion)
As far as I can tell, this happens every time an item is inserted into or taken out of the biolab.

To reproduce:
1. Start a new save and enter editor mode
2. Place a biolab (without energy supply) and unpause (the pollution graph will show up)
3. Insert science into the biolab by manually pressing Y multiple times and see the pollution graph grow higher (still showing 0.0). At the same time, the internal energy buffer of the biolab in the tooltip will get less with each insertion.
4. When the internal energy buffer is empty, the biolab will stop emitting pollution on inserting more items.

Thanks for the report. This wasn't specific to biolabs and just "labs" in general. It's now fixed for the next release.
