Open projections with accessors not following JavaBeans Spec naming identified as closed projection

Consider the following interface projection:

```
interface OpenProjection {

	@Value("#{@greetingsFrom.groot(target.firstname)}")
	String hello();
}
```

`ProjectionInformation.isCloses()` returns in this case `true` because `hello` doesn't match the Java beans naming convention and isn't considered an input property.
