In Rails 4.2 `#asset_path` has changed. Prior to Rails 4.2,
`#asset_path` would search all asset directories, and prepend the
appropriate asset type directory name to the result:
asset_path("emoji/unicode/<id>.png")
#=> "/images/emoji/unicode/<id>.png"
However, In Rails 4.2 `#asset_path` doesn't do that anymore, and assumes
that you've specified the correct folder. Since Emoji images are copied
to public/images/emoji/unicode, `#asset_path` would then generate the
wrong URL path:
asset_path("emoji/unicode/<id>.png")
#=> "/emoji/unicode/<id>.png"
Using `#image_path` fixes that, because that method looks specifically
for images/ folder, so it will find the Emoji images.
