Null tag added to array

[geoffreyvd]

Bug description:

When you have selected the first value in a tag choice dropdown, while the input box is empty and than use the up arrow and hit "enter" there will be a null value added to the array.
Full story: insert any letter: "k" than a dropdown with suggested tags will be represented. Now hit "backspace" and hit "the up-arrow-key" and hit "enter".
A null tag is added

Link to minimally-working plunker that reproduces the issue:

The select/tagging demo from the wiki: http://plnkr.co/edit/v5S1ILJXamIBc83WIMMJ?p=preview

Version of Angular, UI-Select, and Bootstrap/Select2/Selectize CSS

Angular:
1.5
UI-Select:
1.9.5

I fixed the bug simply by changing line 689 from select.js in the provided plunkr by changing:
if ( ctrl.activeIndex === 0 ) {
to:
if ( ctrl.activeIndex < 1 ) {

Could you make a pr for this thanks? Also can you verify if this is the same problem (root cause) of #1887
Thanks.
