text: Title: Instapy does not follow the correct amount of people
  Body: ```
  session = InstaPy(username="Username", password="Password")
  session.login()
  
  
  
  
  tags = ['makeup','eyeliner']
  
  session.follow_by_tags(tags=tags, amount=10)
  ```
  
  as you can see, I set the amount to 10 but for whatever reason it follows 19. 
  It first follows 19 people on the hashtag 'makeup' than 19 from the hashtag 'eyeliner'
