No clear all selection button after migrating from Select2 3.

[arning]

After updating to Select2 4.* there is no 'Clear Selection Botton (x)' on the right side of the dropdown.
allowClear: true does not work.
It also does not work for the amd example.

Apart from that it is working wonderfully.

Cheers

Here is a jsfiddle that shows the problem:

The original select2 shows the 'clear selection (x)' button, allowClear works.

The .select2-multiple does not show that button, although allowClear is set to true.

Actually, the amd-based version was done wrong. I'll repair it. here is the demo that shows how it should work. (beside of autopen on close)
