[WIP]: Test fair root

DON'T MERGE THIS MR!!!

It is a test of FairRootManager.

Many unsuccessful calls of GetObject() lead to a segmentation violation.

In this test I only added this code:

for(int iter=0; iter<10000; iter++){ FairRootManager::Instance()->GetObject("BlaBlaBla"); }

to the STS hitfinder.
