Add onErrorListner for SliceLiveData

Browse Source 
SliceLiveData is changed in the framework, where the way it handles null
slices is different. Thus, we handle the case of null slices by adding
onSliceError() to make slice refreshing back to normal and to prevent
from non responding action on slices.
