Loggin in after crating new collections on a new device, deletes collections on former logged in devices!

[ascheucher]

I used Tabox for some weeks and created a bunch full of collections on two computers with active synch.

Then I used another computer, added two collections and only later logged into my account in Tabox. Tabox then synched the two new collections to my other computer wiping all the other older collections.

This is really a bad bug. Lost a lot of information I would have stored otherwise...
