We didn't have a test for a 5xx that didn't contain the ErrorResponse format.

Hmm should this error be considered as if the server is down? I'm not sure if this could be caused by a slow connection...

…er is down (#2368)

### Changes:
- Created `PurchasedProductsFetcherType` to be able to mock and hold
fetchers, even on older devices
- Created `ProductEntitlementMappingFetcher` to abstract injecting
`ProductEntitlementMapping`
- Added logic to `CustomerInfoResponseHandler` to compute offline
`CustomerInfo` after a server error (see #2367). **This is used by all
`CustomerInfo` requests as well as `PostReceiptDataOperation`**.
- Wrote comprehensive `CustomerInfoResponseHandler` tests

### TODO:
- [x] Don't cache offline computed `CustomerInfo`: #2378
- [x] Integration tests: #2501.
