[gatein-dev] PC test update

[Julien Viet]

I moved the portlet container unit tests from the portlet module to  
the test module in order to remove the hack to reuse the portlet  
module test artifact to obtain the classes that contains the unit  
tests (https://jira.jboss.org/jira/browse/GTNPC-10)

The main consequence is to remove the weird behavior of running the  
tests without including the portlet module, i.e without using the  
aggregator pom. So now it is possible to run the unit tests from the  
test module directly.

let me know if you see any weird behavior.

cheers
