Fun fact:
Now that we fix this, the tests were failing because we were doing:
Wait an entity was created -> wait for all entities to be created -> get the total of queried entities

That's because before, we needed to wait for a first entity to be queried, and then wait for the rest of entities, that way, the tests could wait for every entity to load and pass. Now we just wait for the loader component to disappear, because the load of the entities is faster :-)
