Bug 15572: Follow-up to fix error on authority creation

Bug 6657 modified the way C4::Biblio::TransformHtmlToMarc operates in order to
solve an issue occuring during biblio record cataloguing. But this function is
also used by authorities cataloguing, and the code in this case is irrelevante.
This followup allows to distinguish for which kind of record
TransformHtmlToMarc is called: biblio/authority.

A bug appears in authority creation without this patch in some circunstances:
when authid is linked to 001 field.
