Bugs Fixed

• Resolved memory leak issue with CancellationTokenSource usage not being properly disposed, namely in the following areas:
  • TransferOperation disposes the CancellationTokenSource after transfer reaches a Completed or Paused state
  • TransferManager uses a CancellationTokenSource also does not link theCancellationToken passed to it's methods
  • Removed usage of CancellationTokenSource from handling the chunking of large transfers. This only affects transfers that cannot be completed in one request.
• Fixed bug where cached referenced TransferOperations from the TransferManager were not being cleared on dispose.
• Fixed bug where referenced TransferOperation from the transfers stored in the TransferManager after they reach a Completed or Paused state where not being removed.
