A little fix to upload.py

get_current_emoji_list function had a greedy quantifier in regexp: "data-emoji-name=\"(.*)\""
I.e. for string like
`data-emoji-name="parrot" data-action="emoji.remove"`
it returns following result:
`parrot" data-action="emoji.remove`

In case of lazy quantifier ("data-emoji-name=\"(.*?)\"") the result will be correct:`parrot`
