Traceback if Cuckoo API sends invalid response

If the Cuckoo API sends an invalid response we run into an exception and log it (non-fatally):

urllib3.connectionpool - (Worker-1) - DEBUG - http://127.0.0.1:8090 "POST /tasks/create/file HTTP/1.1" 200 22

    if task_id > 0:
TypeError: '>' not supported between instances of 'NoneType' and 'int'
peekaboo.sample - (Worker-1) - DEBUG - Adding rule result Result "failed" of rule RulesetEngine - Rule aborted with error, analysis continues: No.
peekaboo.sample - (Worker-1) - DEBUG - Current overall result: Result.unknown, new rule result: Result.failed

So it is rather an annoyance than a bug.

As the backtrace says, we're expecting task_id to have an integer value but it is None. We should fix that to avoid the annoying backtrace.
