ConversationService returns unread conversation even if all messages of it have the flag "read" = true

[sasfeld]

Reproduce

1. See webapp log: http://pastebin.com/865cZBrJ
2. Look for the first request: https://api.neeedo.com/conversations/d8f087df-8db3-4a11-b4c0-13d6aa59d0ea?read=false -> here we request unread conversations
3. Now, the user toggles the conversation and expects to get unread messages, so we sent the following request: 'https://api.neeedo.com/messages/b0bce0f5-b89f-4f09-a5d0-0ffd972b15b2/d8f087df-8db3-4a11-b4c0-13d6aa59d0ea
4. The API returned the following JSON

Problem

Look for "read" flags: it is true for each message.

Desired solution

So the conversation request with read=false shouldn't return this example conversation at all.
