ngClass bug in 1.2.16

[CesarAfonso]

Hi,

According to angularJS documentation, ngClass behaves like this :

1º - If the expression evaluates to a string, the string should be one or more space-delimited class names.
2º - If the expression evaluates to an array, each element of the array should be a string that is one or more space-delimited class names.
3º - If the expression evaluates to an object, then for each key-value pair of the object with a truthy value the corresponding key is used as a class name.

In the third scenario, until angular version 1.2.16, the scenario worked properly.
Ex in angular 1.2.15 : http://jsfiddle.net/greenhawk/bS4nV/

We have a class 'green', and we change the other classes based on a scope variable. So we could had 'green italic bold' or 'red italic bold'.

But this new version, 1.2.16, introduces an issue. In this version, the classes that are repeated in both scenarios are omitted. Like 'italic bold'. The ngClass only switches between red and green.
