[HttpFoundation][NamespacedAttributeBag] Refactoring of resolveKey() method
[Console] Added status code to CommandTester and ApplicationTester

Theses classes are already statefull. They contain the input and the
output data. So we can safely add the last status code to the class.
[Console] Add clear() to ProgressHelper.

One may want to print something else while the progress bar is running.
The output will be messy if the progress bar is not removed first.

One may also want to remove the progress bar after the work is complete.

Test case was introduced in 45b68e02bd5838c0288db360ce117b714f9ceaca.

It's probably better to be explicit rather than to rely on a path position in the array. Position in 2.1 was different than in the other branches.
