Fix crash with tuple concatenation onto list

[TabulateJarl8]

Hey! I was trying to exclude files from my upload with codecovcli -v upload-coverage -d --exclude tests and I got the following error:

Traceback (most recent call last):

TypeError: can only concatenate list (not "tuple") to list

On further inspection, I'm guessing that click is producing a tuple instead of a list when creating the contents of the exclude argument. If you want this fix to be implemented further up the call chain, feel free to just close this PR, but I figured if this works then it took about 5 seconds to fix so I implemented it this way. This already has the error checking for if folders_to_ignore is None and I'm just casting the tuple to a list.
