Tests: fixed test preconditions in proxy_cache_lock_ssi.t.

Made sure that a proper request order exists between /locked and /ssi.
Previously, request /locked could be proxied after subrequest /active,
losing in the limit_req race.  Also, request /locked was not properly
delayed, thus proxy cache lock could not happen later in a subrequest.

This somewhat reverts 714668aea2b0 as now inapplicable.

While there, fixed a typo.
