Node agent: answer a proposal's candidate keys and follow the seat's placement, not the indexer's groups (issue 1126)

The answer names its proposal and the revision of the node's own candidate key; a node with no key in a proposal is not asked. The watch for its own placement key is tried again until the seat's state exists, so the node switches when its key is written.
