list index out of range after calling .related_queries() method

[ivanprjcts]

Hi :)

It looks like .related_queries() method is broken. Sample code:

from pytrends.request import TrendReq


keywords = ['real madrid']
pytrends = TrendReq(hl='en-US', geo='US')
pytrends.build_payload(keywords)
related_queries_df = pytrends.related_queries()

Traceback:

Traceback (most recent call last):
  ...
  File ".../pytrends/request.py", line 450, in related_queries
    req_json['default']['rankedList'][0]['rankedKeyword'])
IndexError: list index out of range
