[0.8] x-repeat objectizes arrays of strings

[mbleigh]

<template is="x-repeat" items="[[package.tags]]">
  <span name$="[[item]]">[[item]]</span>
</template>
<script>
  var package = {
    tags: ['first', 'second']
  }
</script>

This will cause the name attribute to appear as name=""first"" and typeof $0.name would be object because it's a String object.

This is fixed on master; primitives are no longer upgraded to their object counterparts in place.
