cssnode: Set new style if it's animated

Browse Source 
In commit 2c61316677 we avoided emitting
the style-changed signal if no CSS property changed.

Unfortunately, this also caused CSS styles to not be updated when
animations started if those animations did not change any CSS value
immediately. In those cases the animation would just never start.
The obvious example was the spinner.
