[tests] Add tests for router store

[frankrousseau]

Here are unit tests for the route store.

I skipped three tests:

• ACCOUNT_CREATION_SUCCESS action test because it requires 5s to be tested properly
• gotoNextConversation() and gotoPreviousConversation(), I don't understand how they work and what they do.

@frankrousseau : gotoNextConversation get the next conversation of the current message into the message list. Into messageStore only messages are saved; the conversations are not natural: we have to find the next message with a different conversationID. Is it clearer?

Same pattern for getPreviousConversation.

[frankrousseau]

Ok thanks. So, it looks broken. When I get next conversation, it always returns the same message whatever the conversation it belongs to.

@frankrousseau : ACCOUNT_CREATION_SUCCESS doesnt exist; you mean ADD_ACCOUNT_SUCCESS?

[frankrousseau]

Sorry but no, the convention for Cozy javascript files is two-spaces indentation.

[frankrousseau]

Thanks for the review and comments. I will handle or answer to all of them soon.

[frankrousseau]

I think I handled all your comments by fixing code or answering them. Before asking for another review, I need to add ROUTE_CHANGE tests and try again to do getNextConversation and getPreviousConversation tests.

[frankrousseau]

I added the missing tests. I think we can go for the merge. I will open another PR soon to make sure that everything runs well with the recent changes made on the store.

@frankrousseau: sorry for the delay, I have missed your comment; i'll check this today.

@frankrousseau: Except my last comments, everything is OK to me; i'm waiting for your answers et eventually changes and then I could merge 👍
