fix: empty emotional state bars from being shown

* fix views for emotional state bars so that they are visible only when
> 0
* add entry_without_emotional_state factory
* add tests for emotional state bars
* remove .all from users_controller since its redundant

Basically stop this from happening (see empty anxiety bar)
