LPS-50604 Fix Wiki imports in DataFactory class

Hi @migue 

This is the Wiki's PR. It's failing during execution time because a NPE in Friendly URL mapper (I'm investigating it). 

Nevertheless I send it to you because I've changed DataFactory imports and, also, portal-tools is not compiling because it's missing the reference to Wiki project. I've tried to set it up inside the build.xml file but it doesn't seem to work, so I'm not sure how it should be fixed.

Have a look at it and don't forward it to Brian until I fix the errors.

Thx,
Ivan
