Failing test for multiple smiley emoticon

[leoasis]

This is a failing test case for #48

As said there, the problem is that the named emoji pattern matches :D: but it's not a valid emoji, and then the correct smiley pattern is not tested.

Haha the test name is really funny

Looks like @leoasis is right, we should be able to fix this by making sure we match :D etc before :([a-z0-9A-Z_-]+):, which will swallow up everything.

[hassankhan]

Do you think you could maybe give it a go @trevorah?

[trevorah]

Yep, it just requires a little bit of time as npm test doesnt give the best output if things error out.

Awesome, thanks! 😄
