refactor(erc): lift cj/erc-generate-buffer-name out of :config

The buffer-name function lived inside the erc use-package :config, so it was unreachable under make test (no package-initialize). Move it to top level; :config keeps the erc-generate-buffer-name-function setq. Adds unit coverage for the server-and-channel, server-only, and missing-piece cases.
