Add "time spent" admin logging.

Mechanism is general, but current implementation only used
for Zurich.

 - Zurich: Record time_spent field mysociety/FixMyStreet-Commercial#676
 - template changes (including jQuery spinner)
 - backend changes to save data are made:
    - in log_edit, if supplied
    - and time on category change (and arbitrary actions)
 - Add update_admin_log to all paths for DM, ensuring that it gets called,
     while resetting the `time_spent` parameter, to make sure that
     there is never a duplicate record created.

 - Also quell warning about using DateTime values in query.

 - Also add (seemingly unrelated) parens to stop misparsing of OK line in
    questionnaire test now that DT::Format::Pg is used in Zurich cobrand
