Bug 27281: (QA follow-up) Fix Indexer Test

With bug 27281 we removed a call to reset an items holdingbranch back to
the 'frombranch' of the transfer.  This is correct, as with bug 23129
(and friends) we ensure that the holdingbranch was not changed at
transfer request time and instead would only be updated at the reciept
of transfer. As such, it's safe to remove the update here as it would be
just setting the same branch as is already present.

However, when removing this ModItem call, I neglected to realise that
also remoes the requirement for passing around the defered indexing bit
as we no longer need to trigger a re-index as there's not any change to
the item.

This patch therefore cleans up the POD for LostItem, removes the no
longer references 'params' parameter and drops the corresponding index
test.
