Fix VTU don't return key property to event when use trigger.('eventName.key') (#1808)

* Add key to events

When trigger 'keydown.tab` - key does not exists.  This affect case when in components we use w3c-keys for compare

* fix: pass key proprety to event

* refactor: remove console.log

* fix: test describe
