Title: bz19228: fix errors with the retry_time column.

Fixed crash when we failed to unpickle status because I spelled
"StandardError" wrong.

Fixed the underlying issue which was that we needed to support unpickling
datetimes in the database upgrade.

Lastly, fix the column type for retry_time so that it actually works.
