Bug 21608: (QA follow-up) Rename revert button

Bug 21608: (QA follow-up) Rename revert button

The label 'Revert found status' is replaced by 'Revert waiting status'
or 'Revert transit status' depending on hold.found/hold.intransit.
Note that hold comes from reserveloop in request.pl. The columns/keys
found and intransit are just booleans.
