minimum-input-length with refresh-delay causes problems

There is a bug using refresh-delay and minimum-input-length in combination.
I've created a plunker http://plnkr.co/edit/D1NQYP8qBfQuUskak7Ei

I expect the refresh function should not be called with search strings shorter minimum-input-length

Hi,
had a look at your issue but I cannot really reproduce the issue you are (i believe) described. So i filled a couple of random characters in (more than 5) and the refresh function worked. Deleted everything, no refresh, added 1 char no refresh. Until I had entered 5 characters. Could you explain what I'm doing wrong?

Fill in 6+ characters then press & hold backspace. Don't delete them all at once.

So i think i have found the problem you are describing. Basicly the problem comes from this line Line 65

The $select.search value will be the old value and not the newValue. I think this should be the length of the newValue that needs to be compared to the minimumlength. Do you agree on this?

Made a example plunker with this fix. Example fix

Thank you for your support but the problem is still existent in your example.
I think its caused in Line 300 of uiSelectController.
The inputLenght should be checked in the moment the timeout is executed.
Imho the delayed execution of the $scope.$eval(refreshAttr) needs to be skipped if $select.search.length < minimum-input-length.
Something like this should work.

var refreshPromise = $scope.$select.search.length >= minimum-input-length ? $scope.$eval(refreshAttr) : false;

I would do a PR but i cant figure out how to access minimum-input-length in the uiSelectController.
I hope everything was understandable for you.
