Fix build with GCC12: apparently incorrect use-after-free warning
GCC12 is complaining about a use-after-free here, but I don't see it.
In member function ‘void QQmlContextData::release() const’,
inlined from ‘QQmlRefPointer<T>::~QQmlRefPointer() [with T = QQmlContextData]’ at ftw/qqmlrefcount_p.h:181:22,
inlined from ‘bool {anonymous}::contextHasNoExtensions(const QQmlRefPointer<QQmlContextData>&)’ at qqmlpropertycache.cpp:658:29,
