Describe the bug
Using the container.ReadManyItemsAsync(..) function to retrieve multiple documents where the partition key is set to PartitionKey.None throws an ArgumentException with the message
PartitionKey has fewer components than defined the collection resource.
To Reproduce
Call ReadManyItemsAsync in a similar fashion to:
var ids = new List<string> { "0" };
var results = await container.ReadManyItemsAsync(ids.ConvertAll(id => (id, PartitionKey.None)));Expected behavior
No ArgumentException thrown.
Actual behavior
ArgumentException thrown with the following exception.ToString():
System.ArgumentException: PartitionKey has fewer components than defined the collection resource.

Additional context
A call to container.ReadItemAsync("0", PartitionKey.None) works as expected.
