replace_named_moji_with_images doesn't work with aliases

[nmdoliveira]

I'm not sure if this is intended, but I was expecting that replace_named_moji_with_images would work with aliases too. My specific case is :robot_face:: its actual name is :robot: and :robot_face: is an alias. But when I call Gemojione.replace_named_moji_with_images(":robot_face:"), it returns ":robot_face:".

Looking at the source, I suppose it's because the regex used in this method (shortname_moji_regex) is generated from the Index's @emoji_by_code, and aliases are added to @emoji_by_name. Would it be acceptable if aliases were added to @emoji_by_code too? If so, I could make a pull request for that.

Thanks in advance 😄

This would be a good enhancement to add for the gem. Will add it to the backlog. Thanks @nmdoliveira
