js: remove 301 redirect cache fix

This code was required because we messed-up in the past regarding
caching headers. This is not required anymore because the caching set
has expired, so no well behaving user-agent should have remains.

This represents something like 240k requests to the backend (not the
cache) over two weeks. Server load was minimal because generating those
responses is really fast.
