Part 8: Apply generator filtering to actions. Remove duplicate code between old and new rebind

```
private String resolveContentType() {
    Consumes consumes = method.getAnnotation(Consumes.class);
	
    if (consumes != null && consumes.value().length > 0) {
        return consumes.value()[0];
    }
    return null;
}
```
maybe not worth the PR, just a little cleaner
