Bug 11254: make reservoir search normalize ISBNs

When importing records, the ISBN is normalized and stored
into database (see C4::ImportBatch::_add_biblio_fields).  But when
searching with ISBN into reservoir, it is not normalized
(see C4::Breeding::BreedingSearch).  So search does not match.

This patch adds the normalisation to reservoir search.  Also, it
replaces call private method _isbn_cleanup by GetNormalizedISBN,
the correct public method.  Also allows the reservoir search
on ISBN with hyphens.

This is intended to fix only reservoir searches.
