Fix GC-related crash in QScriptValue::setData()

Yet another missing API shim.
When converting the QScriptValue to JSC, a JSCell may be allocated,
which can cause the GC to trigger.
If an identifier (JSC::Identifier) is then garbage collected, the
destructor will try to remove itself from the currentIdentifierTable().
Because the API shim was missing, the identifier table was 0.
It's difficult to create a bulletproof test for this case, but the
attached test is a best effort (it crashes on my machine without the
fix).
