[FAB-2697] configtxgen crash mult anchorpeers

https://jira.hyperledger.org/browse/FAB-2697

When multiple anchor peers are specified, the configtxgen tool is trying
to create multiple anchor peers structures rather than a single
structure containing all of them.

This CR resolves this by adding only the entire set of anchor peers,
only once per application org.
