Fix tst_qqmlcomponent::onDestructionLookup

Don't rely on the JIT generated code to immediately discard and ignore
the return value of createObject(). Instead move that call into another
function that, so that the return value of createObject() is guaranteed
to be invisible to the GC and thus collect the recently created object
as expected.
