v2.0.8

• ci(travis): temporarily don't check on outdated packages
• build(npm): ⬇️ eslint, eslint-plugin-node to keep compatibility with node 6

Not published to npm as there's nothing in the distribution that changes - just devDependencies that don't trigger changes in the production code. Still tagged as a version, though, as this is the last version supporting node 6, and it might be useful to get back to a tag might it be inevitable to patch something that also works in a node 6 environment.
