layerStore.Put(): update digest-based indexes when creating from templates 

When we're creating a layer using another layer as a template, add the
new layer's uncompressed and compressed digest to the maps we use to
index layers using those digests.

When we forgot to do that, searching for a layer by either would still
turn up the original template, so this didn't really break anything.
