Warning about missing property which is inherited from composed behavior

[web-padawan]

When linting a project with iron-lazy-pages element I noticed that linter doesn't recognize property selected which is inherited from IronSelectableBehavior here:

          selected="[[subPage]]"
          ~~~~~~~~

src/components/pages/sandbox-demo-page/sandbox-demo-page.html(29,10)  
warning [set-unknown-attribute] - iron-lazy-pages elements do not have a property named selected.
Consider instead:  spellcheck

Steps to reproduce:

• git clone https://github.com/web-padawan/polymer-sandbox
• git checkout linter-sandbox
• npm i && bower i && npm run lint:polymer

I don't get any warnings like this when linting iron-lazy-pages itself.

I think the root cause here is the way the @polymerBehavior annotation is written in iron-lazy-pages. Sent TimvdLippe/iron-lazy-pages#51 out to fix
