[lucicfg] Slightly improve error messages by removing redundant info.

Instead of reporting the full key (a list of (kind, id) pairs), we report only
the last pair. The stack trace should provide enough context to understand
what exactly the error refers to.

This reduces how many internal implementation details (e.g. composite keys) we
leak to the outside.
