Fix emoji regex

The old regex, adapted from the other plugins, was a bit too open for
matching. This leads to matching something like: `This is a sentence:
[And something with a: in it.]()` which doesn't become a link anymore.
Because the match is: ` [And something with a`.

This patch provides a fix for the regex to only match non-space string
within the `:`'s.
