Sort skin tone emojis last

Problem to solve

When entering for example the very common :thumbsup: emoji, one has to type at least :thumbsu because all 5 autocomplete slots are occupied by the various skin tones of the thumbs-up emoji.

Proposal

Sort the skin tone emojis at the end, so the order becomes:

thumbsdown
thumbsup
...
thumbsdown_tone1
...
thumbsdown_tone5
thumbsup_tone1
thumbsup_tone2
...

This way you can first choose the emoji (e.g. thumbsup) using autocomplete and then you can still add the desired skin tone to that particular emoji simply by hitting backspace.
