Fix map restrictions overlaying issue

[DeeTheDev]

Sometimes there are restrictions overlaying others (usually smaller restrictions - image below). The issues is that some restrictions are loaded above others without order and a member is unable to click on the inner-most restriction layer.

Possible solutions is to order the restriction layers in the backend from largest to smallest in layer area. Then, the frontend can load the smallest layers on top of the larger layers, making it clickable.

@DeeTheDev can you check if this is fixed in #498 ?

@rgalanakis It did NOT fix it.

Good example of what we want to see:

The inner-most smallest polygon is "in front" of the larger layer. There are occasions where it is the opposite and that's were the problem lies.
