Zend\Json\Json::decode null or empty string throw Zend\Json\Exception\RuntimeException on PHP7

Similar to zendframework/zf1#678. ZF1 fix PR on zendframework/zf1#680.

As already told in zendframework/zend-cache#95

• It's a bug in zend-cache that will be addressed by fixed #95: don't try to unserialize missing items zend-cache#96
• In my opinion a serializer (all of zend-serializer and zend-json) should throw an exception in case of trying to unserialize or decode invalid input

Agree as a serializer component we should throw an exception in case of trying to unserialize or decode invalid input.
Those that upgrading PHP5 to PHP7 will need to deal with json_last_error behavior change such that json_decode('') PHP5 return JSON_ERROR_NONE but PHP7 return JSON_ERROR_SYNTAX.

Php changed behavior of json_last_error with major version changing. Component zend-json doesn't change major or even minor version. In my opinion, it must preserve backward compatibility and fix issue on php7. Anyway, component should have the same behaviour on all supported versions of php.
