[cling] Crash when dictionary headers can not be found

[Nowakus]

The newest ROOT version in LCG dev3 nightlies crashes in a situation where the earlier versions (<6.27) printed this message:

   Error in cling::AutoLoadingVisitor::InsertIntoAutoLoadingState:      
   Missing FileEntry for TestClassPrimitives.h   
   requested to autoload type TestClassPrimitives   

Now I see this stack trace instead:

The second crash can be reproduced like this:

 *** Break *** segmentation violation
