Fixed #33700 -- Skipped extra resolution for successful requests not ending with /.

2022-06-02T13:15:04Z

By moving a should_redirect_with_slash call out of an if block, commit 9390da7fb6e251eaa9a785692f987296cb14523f negated the performance fix of commit 434d309ef6dbecbfd2b322d3a1da78aa5cb05fa8 (#24720). Meanwhile, the logging issue #26293 that it targeted was subsequently fixed more fully by commit 40b69607c751c4afa453edfd41d2ed155e58187e (#26504), so it is no longer needed. This effectively reverts it. This speeds up successful requests not ending with / when APPEND_SLASH is enabled (the default, and still useful in projects with a mix of URLs with and without trailing /). The amount of speedup varies from about 5% in a typical project to nearly 50% on a benchmark with many routes. Signed-off-by: Anders Kaseorg
