LV2: Reset state on activate.

This makes sure all internal parameters are initializet to sane values
before processing starts. The VST version does this on construction, but
it seems better (at least for LV2) to do this as part of the activate
callback.

This should fix noise on the start of the audio processing with the
plugins.
