Bug 26281: Add cancellation reason to holds history

Bug 25534 adds the ability to store the cancellation reason when a hold
is cancelled and communicate it to the user. It would be great if the
cancellation reason could also be shown on the holds history.

Test Plan:
1) Apply this patch
2) Cancel a hold with a reason
4) Browse to holds history for the holds' patron
5) Note the reason shows in the status column if one was provided

Working ok.
