[PATCH] t/feed: fix uninitialized variable warnings

[Eric Wong <e@80x24.org>]

These warnings only happened under test conditions and never
when running under any PSGI servers.  In retrospect, t/feed.t is
likely redundant nowadays and ought to be folded into existing
PSGI tests so we don't have to consider setup problems like
these.

Fixes: bbe582cdfa429 ("view: fix addr2urlmap with Plack::Builder::mount")
