fix: Prevent deadlock in findOrCreateVaadinSession (#12355)

It is possible findOrCreateVaadinSession leaves session locked if HTTP session is invalidated in an another thread between lockSession and unlockSession calls. This PR changes the implementation so that this can no longer happen.

fixes: #12352
