Replaced list comprehension with generators

[mrcatspoon]

Hi! I’ve made some small improvements:

1. Replaced list comprehension with next(filter(…)). In this case we won’t iterate over every rule and really return the first rule matched
2. Replaced list comprehension with any(). In this case any() will return True when it founds first required attribute in rule object
3. Fixed small typo in reponse -> response
