Remove v4 multilevel transitional currentValue workaround in zwave_js (#45884)

* Remove v4 multilevel transitional currentValue workaround

This was only needed because the get-after-set was reporting a
transitional currentValue instead of the final one.
zwave-js v6.1.1 removes the get-after-set functionality completely, so
this is no longer required (and breaks status reporting entirely)

* Fix tests to check currentValue instead of targetValue as well
