bug: lastEmojiSet is never used (#406)

## Description:

In the existing code, lastEmojiSent can only ever be set if it is
already set, causing it to never be used. This change updates the logic
to work as intended.

## Please complete the following:

- [x] I have added screenshots for all UI updates
- [x] I confirm I have thoroughly tested these changes and take full
responsibility for any bugs introduced
- [x] I understand that submitting code with bugs that could have been
caught through manual testing blocks releases and new features for all
contributors

## Please put your Discord username so you can be contacted if a bug or
regression is found:
