Remove EPSG to URI translator in GeoSparql model.

[Fransiro]

Now for resources, that havent CRS property, the GeoSparql model translate the defautl_projection to a part of URI that is into WKT Text.
If this WKT contains this URI the application draw this WKT. Other case ignore it.
This function prevents draw resources that is in other EPSG or duplicates.
I need to talk with Oscar to solve the problem in another way.

Posible solutions:

-Force resource to have crs property (http://www.opengis.net/ont/geosparql#crs).

-Other way to filter resources by default projection.
