Steps to reproduce :

• call QInAppProduct::purchase() on registered product
• system dialog show up, validate purchase
• system dialog closes
• signal QInAppStore::transactionReady should be triggered but don't

Note : restart my app leads to call restorePurchases() and so a signal transactionReady is triggered with previous purchase informations, I mean flag transaction->status() is PurchaseApproved. It does do it one time only. It behavior like transaction was in queue but have to call restorePurchases() to dequeue the event...

Note : there is no feedback even if user cancels purchase workflow.

The big issue with this is that user purchases well but after dialog closes app has to be restarted to be notified.
