[Qt] Sometimes QScriptValue::isObject returns an incorrect value

[Jędrzej Nowacki]

Example:

bool foo() 
{
    QScriptEngine engine;
    return engine.evaluate("1").isObject();
}

Function foo() returns true. It seems that isObject() function call automatically converts a primitive value to a corespondent object wrapper. Issue is visible only if the value is returned as result of evaluate call. This: 

bool foo() 
{
    return QScriptValue(1).isObject();
}

works correctly.

Fix v1

Proposed patch depends on 34850

Looks good, except for the misspelling in the doc for refineJSValue ("retruns"), and I think it should say "Refines the state of this ... and returns the new state". No reason to use different wording in the description when the function already has a descriptive name.

Done.

As previous patch this one is dependent on bug 34850, that means it cant be applied right now. I have tried apply it on trunk;
~/dev/WebKit$ git apply -v /tmp/isObjectV2.diff

void tst_QScriptValue::toString_initData()
{
    QTest::addColumn<QString>("expected");
