Don't evaluate only overlapping entities

[Joozty]

I can see that EntityLinker evaluates only overlapping entities. I think it should also take into account an entity that is wrongly predicted within the gold data entity and count it as false negative (:man_shrugging:)

Example (it's kind of dummy but I hope you will see my point):

Gold data:
I watched a movie called blue car

Prediction:
I watched a movie called blue car. (wrong prediction and it's not taken into account in evaluation)
