riddiculous redirect for a most basic request

so when asking denser about /@gtg/hello-world, it does a 307 (TEMPORARY) redirect to /undefined/@gtg/hello-world
which is wrong on many levels:

• 1. undefined tag
• 2. 307 vs 302
• 3. doesn't return same response at denser in body

FYI:
Condenser does 302 redirect and returns this:
Redirecting to <a href="/introduceyourself/@gtg/hello-world">/introduceyourself/@gtg/hello-world</a>.
with location: /introduceyourself/@gtg/hello-world

(btw, a whole different story would be a discussion if we should keep the tag in url over having a canonical link as simple @user/permlink and redirect the other way around, but we are very far from being able to focus on that part)
