ProgressController recalculatePercentage bug

[JDeuker]

AngularJS v1.4.5
angular-ui-bootstrap Version: 0.13.4

What to do:
See plnkr demo: http://plnkr.co/edit/zf2jb4?p=preview
Go inside the first textbox (100) and use Backspace to reduce it to 10.

The Problem:
The Bars are recalculated wrong.

The Origin:
First the watcher for "max" is proceeded for both bars.
Next the watcher for "value" is proceeded for only the first bar.
While calculating the totalPercantage the second bar has still the wrong percentage. See:
var totalPercentage = self.bars.reduce(function (total, bar) {
return total + bar.percent;
}, 0);

The Solution:
Recalculate the bar percentage:
var totalPercentage = self.bars.reduce(function (total, bar) {
bar.percent = +(100 * bar.value / bar.max).toFixed(2); //Bugfix
return total + bar.percent;
}, 0);

This sounds reasonable, although I'm a bit worried as to why the unit test does not capture this situation - can you file a PR with this fix?

There is also a problem with removing an item, because recalculatePercentage is still calculated with the removed one included.

I found a solution with recalculating after removing:
this.removeBar = function (bar) {
this.bars.splice(this.bars.indexOf(bar), 1);
this.bars.forEach(function (bar) { //Bugfix
bar.recalculatePercentage();
});
};
