Restore-AzCosmosDBAccount cannot restore from deleted CosmosDB Account anymore

### Description

In the version **Az.CosmosDB 1.10.0 or above** the Restore-AzCosmosDBAccount does not allow restore from deleted CosmosDB Accounts (except the oldest one). There is a warning "**No database accounts found with matching account name cosmos-aa-bb-cc that was alive at given utc-timestamp"**. In version **1.9.0 it works with no issue**. In both cases Get-AzCosmosDBRestorableDatabaseAccount displays the current and also all the deleted CosmosDB Accounts. It has been tested with multiple CosmosDB Accounts.

Start at the Restore-AzCosmosDBAccount entry point and reproduce the warning with a deleted Cosmos DB account using the script and module versions in the report. Compare behavior between Az.CosmosDB 1.9.0 and 1.10.0 or later; done means restoring a deleted account at the specified UTC timestamp succeeds rather than reporting no matching account.
