Apply first Set-Cookie header instead of the last. Experimental.

Some sites (e.g. [1-3]) may serve two cookies under the same name
in Set-Cookie header and expect the first (old) one to be set rather
than second (new). However, as of RFC6265 the newer one cookie
should be set into cookie store what actually happens.
We will workaround this issue by resetting the cookie to
the first one manually.
