LadspaControl: set name property for tempoSyncKnobModel

For each model but the tempoSyncKnobModel the name property was properly
passed to the according constructor. This made time-based knobs in LADSPA
effects have no internal name, e.g. there were blank captions in the
knob's context menu or empty titles when used in combination with
automation patterns.
