Clean function does not work with multiple emoticons.

Hi my name is Steve and I am currently learning Elixir.
I stumbled upon this repository and decided to read the code to learn more about Elixir.

I tried to run the code with the following string:

iex(4)> Veritaserum.analyze("Hi I am filling😰 but my friend is😊", return: :score_and_marks)
{-1,
 [
   {:neutral, 0, "hi"},
   {:neutral, 0, "i"},
   {:neutral, 0, "am"},
   {:neutral, 0, "filling"},
   {:emoticon, -2, "😰"},
   {:neutral, 0, "but"},
   {:neutral, 0, "my"},
   {:word, 1, "friend"},
   {:neutral, 0, "is😊"}
 ]}

My assumption "is😊" should be separated from what it does with "filling😰".
If my assumption is correct, then this line of code should be fixed, with the following:

|> :binary.replace(Evaluator.emoticon_list(), "  ", [:global, insert_replaced: 1])

The updated code result:

iex(3)> Veritaserum.analyze("Hi I am filling😰 but my friend is😊", return: :score_and_marks)
{1,
 [
   {:neutral, 0, "hi"},
   {:neutral, 0, "i"},
   {:neutral, 0, "am"},
   {:neutral, 0, "filling"},
   {:emoticon, -2, "😰"},
   {:neutral, 0, "but"},
   {:neutral, 0, "my"},
   {:word, 1, "friend"},
   {:neutral, 0, "is"},
   {:emoticon, 2, "😊"}
