Got an unexpected keyword argument 'path' when deleting a repository tag

[hex108]

I run docker registry with Redis enabled, and I get following errors when deleting a repository tag.

TypeError: wrapper() got an unexpected keyword argument 'path'

It is caused by the wrapper @lru.get() that decorates function store.get_content() does not deal with **kwargs.
