I've fixed this with another defined() check.

I've fixed this by adding a name - it's required (by xhtml) for all
form fields, so it's not really a problem that there's warnings with
no name.

I've also found by looking at the source of `prove` that it supports
passing the -w flag to the test files (it's undocumented) - so I've
added an alias to ensure the tests now always run with warnings
enabled.
