fix($compile): ensure CSS classes are added and removed only when necessary

When $compile interpolates a CSS class attribute expression it will
do so by comparing the CSS class value already present on the element.
This may lead to unexpected results when dealing with ngClass values being
added and removed therefore it is best that both compile and ngClass delegate
addClass/removeClass operations to the same block of code.
