Testing - File Deletion

- Add tests for file deletion
Enhancement: Mixed results in deletion of multiple blocks

- Added test to mix the results of deleting the list of blocks
--- requires that the result from DeleteBlocks() be more explicit about the meaning of the list since nothing is guaranteed in the sort order
----- updated other tests as appropriate

- Set the limit to match what was requested as that would be more accurate to what Deuce returns
