Fix bug in CreateOrOpenInternalAsync when recursing into a partition
Fix tuple StartsWith and EndsWith. It was using == instead of Equals, which became a ReferenceEquals check when a[i] and b[i] were typed as objects.
Passing in an empty prefix now results in an error
Use object.equals to test for equality
