Remove event emits full ng-select model instead of direct value

[emir7]

Describe the bug
It seems like the remove event emits the whole NgOption object instead of its value property.

To Reproduce

1. Select an arbitrary item
2. Deselect previously selected element
3. Inspect emitted value from (remove) event.

Expected behavior
I would expect that the value emitted from the remove event should contain direct value of the item passed by the user to the items array - the same structure as its counter part add event emits.

@emir7 this expected behavior. Not all options are strings

@pavankjadda i'm sorry, what exactly do you mean by "not all options are string"? In this particular case full NgOption model is emitted instead of its value

My bad. You are right. Will merge the PR
