Can not change QML camera device if it is supported by another media service provider plugin

I use two media service plugins for camera at the same time. One is a standard CameraBin and the other is [qtmultimedia-gphoto|https://github.com/dept2/qtmultimedia-gphoto].
QML camera allows you to specify the deviceId only supported by one of the plugins. If you try to change the deviceId to a device supported by another plugin, it will not work. This is because the QCamera object created in the QDeclarativeCamera constructor always returns QMediaService object of the first plugin it finds.
