Reviews in/out

Summary

The reviews counter, in & out both, do not work. They seem to return an empty array, eventhough I have got some reviews.

Steps to reproduce

1. Open canvas.hu.nl
2. Open your Portfolio
3. Open Learning Analytics
4. Duhh

What is the current bug behavior?

Review counters both shows 0, even though I have more than 0 reviews in and out.

What is the expected correct behavior?

Showing a number above 0 in either counter.
