Fix issues with updated emoji mart (#7761)

* Changes behavior from search light to keep custom search
The new version of emoji-mart needs the search function to constantly
receive the custom emoji array. This changes the behavior back to the
previous one in the search light method to keep the emoji autocomplete
as before

* Change test order
The order was breaking the tests

* Fix codeclimate issues

* Update to emoji mart to version without issue in picker

Fixes #7760
