ReferenceChecker should handled the inputFiles the same for the checkDir: than the checkProject:.

Right now

• checkProject: is looking for the transitive closure of the files via inputFile (using the fileCollector)
• checkDirectory: does not look for the transitive closure and this is not good.

both checkProject: and checkDirectory: should have the same semantics.

We should add a test clearly showing that they is not difference once this problem is fixed.

checkProject: is basically looking for all the files it can reach starting from an input. When making checkDir: using the same logic with all the files in a directory, the worklist should be shared among all the files in checkDir: to avoid to treat files multiple times (it could happens if we have several files in the directory pointing a same inputFile for example).

We should check the PR of Quentin because I have some doubts.
