Too much regressions since PR #823, #814 (applications states are not reflecting routes); move all states related to route into routerStore.

Fix features

• [x] right panel should be closed when a message is closed,
• [x] when mailbox changes (click on mailbox link) messages should be updated,
• [x] button load more should load next messages if they exists, otherwise do not display the button.
• [x] FIX infinite load on trashMailbox,
• [x] goto nextConversationwhen a message is deleted,
• [x] fetch all messages when showing a conversation,
• [x] fetch messages until selected message is found,
• [x] fetch all conversation when displaying a message,
• [x] a message detail is closed when use click on mailboxLink,

  Add feature

• [x] add counter to flaggedMailbox,
• [x] add paginate information (not visible but exists into RouterActionCreator).

  Clean

• [x] replace RouterActionCreator.navigate by other actions

@frankrousseau : this one has became more important than others; #828 must be the next one to implement @m4dz review, then #817 is the next, and #825 might not be finished at the end of the sprint. I would close #825 tomorrow if review take too much time

Seems you've got a problem in your recent rebase : we've got code from 22 days ago. There's something wrong, nope ?
