test: drop tenant repo name from the epics fixture (tenant firewall)

The `_EPICS` fixture named a tenant repo twice, which trips the tenant-firewall
check — organ code must not carry instance facts. Reworded to the synthetic
name the rest of the file already uses. No assertion depended on it; only
"PROGRAMME.md" and the epic title are asserted.

The firewall runs on organ-repo PRs, so this was failing CI beyond this repo.
