Fix clearing two cookies with the same name #3207

This is an ugly workaround, and it might go wrong other code tries to manipulate the same cookies for the same response. But at least in my testing, it fixes the issue reported in #3196 .

I think a properly robust fix would involve replacing http.cookies.BaseCookie with something that can handle multiple cookies with the same name. But Tornado appears to consider it a corner case that's not worth supporting (tornadoweb/tornado#1248), and it seems like a lot of work for us to build that just to tackle this one bug. Then again, it is a security bug, so maybe we should be taking that time.

Closes gh-3196

if path and path != '/':
# also clear cookie on / to ensure old cookies
# are cleared after the change in path behavior.

Maybe just call the force_clear_cookie here so we are using the normal clear_cookie most of the time? And add a FIXME noting that this is a backward-compatibily bit added in 5.2?
