Title: Don't bother respecting Accept if we only have one renderer (bug 956860)

https://bugzilla.mozilla.org/show_bug.cgi?id=956860

The performance win is probably minimal, but maybe we should try this? The default negotiation class loops over `Accept` values to find an appropriate renderer but we don't particularly care about that, since we only support JSON anyway.
