fix: Advanced filters does not contain tags after first tag was added (@Rowan441) (monkeytypegame#7025)

### Description

fixes monkeytypegame#6972

The setup logic for the "tags", "funbox", and "language" advanced
filters are only run on the first load. So adding a tag in the /settings
won't make the "tags" multiselect render when you navigate back to the
/account page unless you reload.

Added logic to add / destroy the "tags" multiselect if you create your
first tag or delete your last tag.
