- following c3fd91670e `paste` has been typoed into `pase`
- adds two tests for pasting in `multi-select` and `email-group-user-chooser`
- selectKitOptions would not be following the right overriding order
- `category-selector` was using `selectKitOptions` directly which shouldn't be the case as it's not using computed values
- apparently since a recent ember upgrade, paste event is not providing `originalEvent` anymore and `clipboardData` should be retrieved directly on the event
* Use QUnit `module` instead of `discourseModule`
* Use QUnit `test` instead of `componentTest`
* Use angle-bracket syntax
* Remove jQuery usage
* Improve assertions (and actually fix some of them)
This is where they should be as far as ember is concerned. Note this is
a huge commit and we should be really careful everything continues to
work properly.
