docs: is called when the ViewHolder is in a transient state. return true if you want to reuse
  that view anyways
  
  @param viewHolder the viewHolder for the view which failed to recycle
  @param position   the position of this viewHolder
  @return true if we want to recycle anyways (false - it get's destroyed)
