Crashes in SDK (placements)

[levochkaa]

Started to appear after updating from 3.2.8 to 3.3.2.
My guess is that storeKitProductsFetchedCallbacks can get the same callback twice, somehow.
The stacktrace is always the same for us, we call only Apphud.placement on our paywall appear/disappear

This was happening very rare when using await method of placements(). Fixed in v3.3.6. Thank you!
