Avoid clobbering SBIV colors in NIC

NotificationIconContainer#setAnimationsEnabled can apply a stale cached
icon color to its child StatusBarIconViews, causing incorrectly colored
notification icons in the status bar.

This specific color application is only relevent to the
NotificationShelf; a check is added such that it will not be invoked
for the status bar or AOD icons.
