Blank artifacts when using qml objects

S4 - Minor

Preliminary steps:
- Open MuseScore with the Promenade example.
- Plugins -> Plugin Manager.
- Check "load" for all available plugins.
- Close and restart MuseScore.

Three bugs:
- View -> Synthesizer -> Master Effects.
- Change "Effect A" from "Zita1" to "No Effect".

- Result: blank rectangle, see attached picture.

- Plugins -> scorelist.
- Result: blank gray window.

- Plugins -> ScoreView.
- Result: blank white window.

Notes on -1-:
A debug build shows the following in the command prompt:
Warning: qrc:/noeffect/noeffect.qml:1:1: plugin cannot be loaded for module "QtQuick": Namespace 'QtQuick' has already been used for type registration
Debug: no root object for NoEffect

but only when the other plugins have been registered and added to the menu.
Under Mac, even without loading the plugins both the effects show blank white rectangles.

I believe these are all now not relevant, for slightly different reasons.

1) This now works properly, without error. I am not clear if it because of PR #1246, but I don't think so.

2) & 3) work correctly according to the script code.
2) Prints the score list, just not in the window that it creates, which is an error in the script writing.
3) Doesn't output anything, so a blank window is the "correct" output.

Could someone confirm and close this issue if I'm correct.
