... does it actually have wasps in it?

... and when you say paper wasp nest, do you mean the nest itself is made of paper or the wasps are?

The Feywild Trinket Table doesn't elaborate on that. So I'm going to say it actually has wasps in it (otherwise, the jar probably wouldn't have been included). I think the nest itself is made of paper and the wasps are live. 

Anyways, you have one more try at disadvantage thanks to Brutrumukk's gourd.
