Vending: Fix Purchase API issues

[DaVinci9196]

1. Added a missing checkIn parameter and fixed the missing content returned by the vending detail API.
2. Added deviceConfig API and fixed the issue of the purchase API returning a 400 error.

@DaVinci9196 Am I correct that it will resolve issues with in-app purchases? I have issues with FaceApp - it wont get licence from Play Store (Huawei Device)
MicroG on Huawei no errors, it receives pricing, but can't get licence (or wont get licence):

@beastdrc This fixes a problem with the automatic database entry function and is unrelated to IAP. The issue of IAP failing to launch is addressed in another PR.

Isn't there an option to check before using uploadDeviceConfig?

[mar-v-in]

@ale5000-git This function is only invoked when licensing and auto purchase option are enabled. It remains disabled by default and also only uploads configuration data that is already part of device registration anyway.

@mar-v-in
So it use the device profile with fake data?
