[Form][DateTime] Propagate invalid_message & invalid_message_parameters to date & time

This PR propagates the `invalid_message` & `invalid_message_parameters` in the datetime form type to the date & time sub form types. It allows to have the good error message if you use something else than the `single_widget` widget.

I have looked the `DateTimeTypeTest` but I have not found tests related to this kind of propagation, so for now I have not added tests yet.

[Finder] [Iterator] Make the tests less fragile

Modified the Iterator tests so that they assert only on what's actually being tested. In particular, the tests were checking the order of the files [that were created virtually simultaneously] after sorting them by date. This change is a part of the effort to make Symfony successfully pass tests on HHVM
