Bug 18262: Koha::Biblio - Remove GetBiblioData - part 1

Most of the time C4::Biblio::GetBiblioData is used to retrieve the title
and/or the author of a bibliographic record.

This patch replaces the easy occurrences of GetBiblioData, the ones
where the 2 joins are needed, but only data from biblio and biblioitems
table are.

Test plan:
It will be hard to test everything, I'd suggest a QAer to review this
patch and confirm that the difference occurrences of GetBiblioData have
been correctly replaced by calling Koha::Biblios->find or
$biblio->bibioitem
