Fixed! Thanks!

As discussed offline: its not the main goal of this suite introducing,
also, TAP13 protocol is tested by `prove` itself, and fully compatible
with TAP14 protocol. Also, added the following check of parsing to be
sure in the emmited format correctness.

Also, mentioned this in the commit message:

| The library itself is tested via some primitive tests for `ok` case,
| `skip` and `todo` directives. The TAP13 format is tested via prove, that
| we are using for running our tests. TAP14 format is compatible with
| TAP13, so there are no other tests required.
