Don't require #:duct.reitit/logging{:enable true}

[kkharji]

When enable is false, (not nil) then disable logging totally, otherwise, depended on other keys.

Spent few minutes debugging why I'm not getting coercion errors, while at the same time getting request logs and it turned out that defaults:

  :duct.reitit/logging
  {:level :report
   :exceptions? true
   :pretty? true
   :coercions? true
   :requests? true}

doesn't include enable.

Therefore, when and only when enable is false, then overwrite and disable everything.
