Bug 4397: Scan index search results broken for non-latin characters

The Zoom specification defines that a ScanSet should provide a way
to retrieve terms suitable for displaying and another one for using
on further searches [1].

The Net::Z3950::ZOOM implementation actually provides both [2] but we
where using the wrong one.

Using $scanset->display_term(...) instead of $scanset->term(...) fixes the
problem.

To test:
- Do a index scan search (advanced search > more options > check 'index scan')
- Notice non-latin characters are replaced by one or more '@' symbols.
- Apply the patch
- Re-do the search, everything shows as it should.
- Try to follow any of the terms (clicking on them) and notice that
  it actually gives you relevant results (i.e. is not searching for @!!!!).
- Sign off :-D

I reproduced the issue and I confirm this patch fixes it.
I put "Fuß" in a title, reindex the record. Launch a search on Title
checking the "scan index" checkbox. And the non-latin characters are
well displayed.
