Fix QFileSelector::select if called with QUrl and scheme "assets"

QFileSelector::select(QUrl) will use ":" for scheme "qrc" to
call QFileSelector::select(QString). Scheme "assets" needs
to remain "assets:" for select(QString), otherwise it won't
recognize the file in "assets".

Following failed because it was passed as ":/qml/example.qml"
to select(QString):
    select(QUrl("assets:/qml/example.qml"));

This will call select(QString) to:
    select("assets:/qml/example.qml");
