[DS-3469] virus scan during submission attempts to read uploaded bitstream as anonymous user, which fails (#1632)

Browse Source 
* [DS-3469] Add the current session context to the curation task run.

* [DS-3469] Log how I/O failed, not just that it did.

* [DS-3469] Keep reference to Bundle from which we just removed the Bitstream instead of expecting the List of Bundle to be unaltered.

* [DS-3469] Finish switching from e.getMessage() to e

* [DS-3469] Note the side effect of calling curate() with a Context.
