No cache context or cache tags causing blocks to not re-render on different nodes.

This module has an awesome feature that allows you to render the current page's node in multiple blocks using whatever view mode you want. The issue is that the cache context and cache tags for the block do not reflect the need to have access to the current route's node, so once the block has been rendered once it will cache itself and be used even if the route changes.

I would suggest adding getCacheTags() and getCacheContexts() to the NodeBlock class.
