FIX: Emoji autocomplete “more” button not working in chat (#20113)

* FIX: Emoji autocomplete “more” button not working

* Rely on setting an intial value on the filter input

This commit removes custom logic applied on initial filter and instead gives a param to use as value for the input, automatically triggering the existing filtering handler.

Other notes:
- Slightly changes the API to be able to set a filter and open the composer in one go
- Adds a very simple service spec
- Adds a system spec to fully validate the behavior
