Create menu (#2195)

* Wire up create with old create action

* refactor grid and list view to listen on composition, use lodash for sorts, remove item count

* remove item count on grid view

item count needs to be supported by composition API and not by
inspecting model, otherwise it will be inconsistent.

* close menu after create or clickaway
