tapback with any emoji

[matkam]

What changed?

Instead of a static list of emojis for a tapback, open a sheet with the emoji keyboard, and use the first typed emoji.

Why did it change?

The static list of tapback emojis is too limited.

How is this tested?

Very cool, we may want to use a smaller subset later that works with stand alone devices, but for now android allows the bigger list so this is great.
