CFElements: restore support for legacy sequences

Removing the support for legacy sequences in !70309 was premature as we
still need to support them for Generators and to some extent analysis.

Replace the use of `.name` (which only works for GaudiConfig2) with
`getName()` that works for both legacy and new Configurables.
