fix(test): remove stale TestInstallTownRoleSlots test (#819)

Role slots were removed in a6102830 (feat(roles): switch daemon to
config-based roles, remove role beads), but the test was not updated.

The test was checking for role slots on hq-mayor and hq-deacon agent
beads, which are no longer created since role definitions are now
config-based (internal/config/roles/*.toml).
