md-slider with ng-change displays the wrong tooltip

[PaulMougel]

When the function called by ng-change in an md-slider modifies the model's value, the tooltip displays the old value (the one that was selected by the user), and not the one that was set by the function.

<md-slider flex md-discrete min="0" max="10" ng-model="value" ng-change="stayAt5()" aria-label="Slider"></md-slider>

$scope.stayAt5 = function () {
  $scope.value = 5;
}

See this Plunker.

Edit: I have a fix, I'll send the PR as soon as possible.

I just changed the visual value

.md-sign
{
        &:before
        {
            content:'s';
            color:#fff;
            font-size: 12px;
            font-weight: bold;
            order:2;
        }
}
