Fix tst_qqmlecmascript::scope() and behavioural compatibility with v8 based qml

In the V8 based QML the global object would come _before_ the "QML global object",
which is the QML context (wrapper). We had a bunch of tests that verify the exact
scope chain and with this "compatibility" fix we can re-enable them.

Also fix missing prototype setup for the console object.
