Toolbox getEprintField doesn't work with subfields (but probably should?)

[tmb]

...because Metafield::to_xml doesn't return anything if the field is a subfield (defined $field->{parent_name}).

Workaround:

sub tool_getEprintField
{
        my( %opts ) = @_;

        my @problems = ensure( \%opts, 'session', 'eprint', 'field' );
        return( 1, \@problems ) if( @problems );

        my $field = $opts{eprint}->get_dataset->get_field( $opts{field} );

        # don't ignore subfields
        delete $field->{parent_name} if defined $field->{parent_name};
