[Bug]: SqlRawPersistentBlobCache no valid operation queue in Xamarin.iOS .net 7 when link all set #835
Description
Describe the bug 🐞
After registering the app name with Akavache.Registrations.Start, a call to InsertObject results in a System.InvalidOperationException "There is not a valid operation queue".
SQLitePersistentBlobCache and SQLiteEncryptedBlobCache have been referenced in LinkerPreserve as noted in README. New instances of these classes can be successfully created and referenced (as a test.)
I've also attempted to add --linkskip Akavache to the iOS project properties, including all other Akavache namespaces.
Adding a BlobCache.EnsureInitialized(); after app name registration also didn't help.
Step to reproduce
In project properties set
<MtouchLink>full</MtouchLink>
In app start, register app name:
Akavache.Registrations.Start(blobCacheApplicationName);
Attempt to input a starting object into any cache:
await BlobCache.UserAccount.InsertObject("SuccessfullyStoredValue", true);
Exception will be hit:
System.InvalidOperationException: There is not a valid operation queue

Expected behavior
Operation queue should be initialized after registering app name, allowing an object to be inserted into the cache.
