Bug 14919: (followup) Show accurate status in holds history

This patch fixes the status showed in holds history table.

The determination of status is following:

1. "hold.found is 'F'" - Fullfilled - the hold was fullfilled by checking the
item to patron. If hold reaches this state, it can't changed status
anymore, or be cancelled, that's why this goes first

2. "hold.cancellationdate is filled" - When the hold is cancelled, its
eventually waiting or in transit status remains the same, only
cancellation dat is filled, so this has to go second

3. "hold.found is 'W'" - Hold is waiting

4. "hold.found is 'T'" - Hold is in transit to target library

Test plan:
0) Apply the patch
2) Read the status determination note in this commit message and confirm
it makes sense
1) Have patron/patrons with at least one hold in every status
2) Go to holds history page and confirm it show the right status
3) Try to break the status determination ;)
