Don't crash when scrollTo is called

RecyclerView does not support absolute position scrolling and it throws
UnsupportedUperationException if scrollTo is called.
This may create problems when user implicitly calls these methods (e.g.
via TransitionManager). Now instead, we just log an error and continue.
