Validate note sizes on key-rotation.

We also need to validate the note sizes on key-rotation.
If we do not validate them before we store them, that could lead to a
partial or total loss of the password vault. Validating these
restrictions before actually processing them to store/replace the
existing ciphers should prevent this.

There was also a small bug when using web-sockets. The client which is
triggering the password/key-rotation change should not be forced to
logout via a web-socket request. That is something the client will
handle it self. Refactored the logout notification to either send the
device uuid or not on specific actions.

Fixes #3152
