as_quote_it plugin cause request loop and request timeout

[banjun]

When a message contains permalink to the chat/room or message that contains the original message itself, as_quote_it plugin requests the chat/room or message page to expand permalink. The request cause request loop between AsakusaSatellite and QuoteIt and then the requests will be timed out.

steps to reproduce:

1. post message like http://(AsakusaSatellite_Root_URL)/chat/room/(room_id) . (room_id) is room_id of the messages' target room
2. call /api/v1/message/list or load /message?id=(message_id)

note:
Since messages in /chat/room/(room_id) are cached, /chat/room does not timed out in most cases.
