Bug description

If the User chooses to apply a preset to a native Real Time Effect, then closes the effect, the changes brought by the preset won't be commited.

Note: If default preset is somehow modified, the effects' parameters are retained.

Steps to reproduce

1. Launch AU4
2. Add a mono or stereo track
3. Open effects panel
4. Add reverb
5. Open reverb dialog
6. Select any default preset
7. Close the reverb dialog
8. Re-open
9. Observe result

Expected behavior

Once any default preset is chosen, the effect should use the parameters of the preset.

Actual behavior

The effects parameters are reset upon re-opening the effect if any default preset is chosen.
