fix!: unstable mention value parse with emojis

Optimize algorithm for parsing value. Use String.prototype.split instead of matchAll utility.

Add emojis to some tests.

BREAKING CHANGES: now it's important to use only one group in the part patterns for correct work of `getKeyword` and ``parseValue` methods.
