Crash #2811 fix (#2812)

* Use mutable list to allow updates even when grid is inactive

I don't think this should happen but it does, so this makes it continue
silently instead of crashing.

Fix refinedmods/refinedstorage#2811

* Do not show updated items if there is no full inventory yet

* Ensure gridview list implementation is ArrayList

The update code relies on an indexed mutable list, so that should be
made explicit here.
