fix to immediately view placeholder + set min height

without this fix, "getPayloadForImageLoader" was called before the placeholder was set (so it was null until getPayloadForImageLoader was called again after ~30seconds.). This is fixed by calling the super method at the end of "onBind".

min height was set to avoid very tiny previews (like for the placeholders)
