Description

Setting the cache-id attribute on <platinum-sw-cache> or setting the cacheId property has no effect.

Expected outcome

I expect the cache name as listed on the chrome dev tools Resources -> Cache Storage to include the string I specify.

Actual outcome

It does not include the string I specify.

Steps to reproduce

1. Create a simple web page with a platinum-sw, and add a cache-id attribute :

    <platinum-sw-register auto-register clients-claim skip-waiting>
      <platinum-sw-cache cache-id="999" default-cache-strategy="fastest"></platinum-sw-cache>
    </platinum-sw-register>

1. Run server
2. Open page in browser and open chrome dev tools and look for the name of the cache.
