LadspaEffect: fixed controller connections on samplerate changes

When global samplerate changes, settings of a LADSPA effect are stored in
a temporary object, the effect is reloaded and the settings are restored.
However, controller connections weren't restored properly as the connections
were not finalized. This commit fixes the issue.
