Disabling sync id checking does not work

[TatuLund]

Description of the bug

This bug fix does not take into account the case that lastSeenOnClient can be -1 when sync id checking has been disabled

https://github.com/vaadin/flow/pull/15764/files

This will result putting all messages back into cache repeatedly as alreadySeen returns always false.

This again leads to server continuously pushing.
