test_icon: Clean up icon standard sample.

- Do not set unnecessary min size for the icons. Just follow list's item
size naturally.
- Do not free unnecessary list which was already freed by
EINA_LIST_FREE.
- Do not set align for the window resize object which is not required to
be set.
- Follow conventional way of pointer declaration.
