Greatly simplify the ::Sybase::ASE::insert() override

The _insert sub-method actually isn't used by anything else, and as such is
not needed. The behavior has been verified to be identical by comparing
DBIC_TRACE=1=logfile runs before and after the changes.

Still - there may be dragons, if bisecting pay close attention to this fella
