Morten Sørvig 25c2d05340 wasm: don't access deleted settings objects
The emscripten_idb_async_ functions are async, so there
is no guarantee that the QSettings object which made
the request will be live by the time the completion
callback is made.

Keep track of live QWasmSettingsPrivate objects, return
early from the callbacks if userData does not point
to a valid QWasmSettingsPrivate.

Pick-to: 6.4 6.3 6.2 5.15
