Fix first zap when modal closed (#771) (#1055)

* Fix first zap when modal closed (#771)

 - Extract handlers
 - Remove unnecessary async keyword from callback
 - Assign a new key to force remounting of LongPressable component when modal is closed from long press
 - Remove hover state when closing modal, otherwise it stays colored

* Replace LongPressable with custom component

* Remove yarn.lock
