ansible-lint: Fix key order on upstream tests

In latest ansible-lint versions, the use of "blocks" has a required
order to be implemented. According to ansible-lint error mesage, the
order is name, when, block, rescue, always.

As not following this rule is now an error, this patch fixes all tests
for the 'key-order[task]' error.
