My project consists of three iterations:
- Low-fidelity usability tests
- Redefined prototype usability tests
- Final prototype usability tests.
I am unsure whether to include the HCI expert review session from the first iteration.

I think you should take it one step further than just including them. But yes include them in the review I think having another set of eyes with additional views could help the effort.
Why not include them in the prototype generation?
I am a huge fan of parallel prototyping to increase idea generation. Parallel Prototyping Leads to Better Design Results, More Divergence, and Increased Self-Efficacy
You could do something like google ventures does and include them during the prototype creation process to add to the idea generation process when making prototypes. Check out their design sprints
Possible Reason to leave out experts in low fidelity prototype reviews
A question on your question: If the expert does not understand the first insights being gathered, or could not have influence on probably missing information, how could they create the best possible next level prototype or wireframes?
If you think that you should conduct a test, because you (the expert) do not know enough (which is, well, why you test at all), then the answer is: Yes, absolutely. Because that is why you do it in the first place.
Participating in usability tests is crucial to usability engineers. And, for all the nodders, for the product owners/managers as well.
