commit ab20193ee40d492d9fc4e9974a099830dcf6fe28

Closure compile metadata_cache_item_unittest.

Convert metadata_cache_item_unittest.js to be closure compiled.

- Remove html file that is not auto generated.
- Fix closure errors in the unittest file.

As MetadataCacheItem requires a MetadataItem to be a parameter most of the unit
test code needed to be re-written to use this type.

No change in behaviour.
