[Bug]: SqlRawPersistentBlobCache no valid operation queue in Xamarin.iOS .net 7 when link all set

[MagneticLlama]

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
at System.Reactive.PlatformServices.ExceptionServicesImpl.Rethrow(Exception ) in /_/Rx.NET/Source/src/System.Reactive/Internal/ExceptionServicesImpl.cs:line 19
at System.Reactive.ExceptionHelpers.Throw(Exception ) in /_/Rx.NET/Source/src/System.Reactive/Internal/ExceptionServices.cs:line 16

Expected behavior

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