Fixed order of Likes and Retweets, Removed premature return in `get_user_information()`

[bmeares]

I had opened a previous PR #130 but closed in favor of this one which I've more thoroughly tested. This PR address some simple bugfixes (e.g. wrong variables like minretweets in argparse) as well as some more serious issues like Retweets and Likes being in the wrong columns as well as preventing get_user_information() from returning early during an iteration.
