So you can see that as well as not decoding the output when arg="color", it didn't remove enough lines at the start, so I've increased the slice index from 2 to 5 to fix this.

I've also added some tests.

This also fixes TextClip.search("***", "color"), which expects a list of strings, not bytes and previously failed with the following error:

Traceback (most recent call last):
  File "/Users/tomburrows/Python/moviepy-dev/moviepy/tests/test_TextClip.py", line 65, in <module>
    test_search()

    blues = TextClip.search("blue", "color")

    return [name for name in names_list if string in name.lower()]
TypeError: a bytes-like object is required, not 'str'

• I have provided code that clearly demonstrates the bug and only works correctly when used with this PR
• I have added suitable tests to the test suite in tests/
• I formatted my code using black -t py36
