[IMP] account: remove dynamic domains in register payment wizard

It seems very strange that we'd want to use active_ids as invoices to
work with when when we already have invoices available, and these are
browsed / converted from the active_ids if they weren't provided
explicitly.

There's also an odd divergence between the filtering on the journal's
company here and in the default_get too: in the default_get we get a
journal in the user's company but then we only allow selecting a
journal from the invoices' company...
