test(cluster): spec-5.13 v1.0.3 — renumber t/315 -> t/316 (ship-storm collision with spec-5.15)

spec-5.15's t/315_cluster_5_15_online_rejoin.pl shipped to main first; this
v1.0.3 test (authored on a pre-5.15 base) collided on number 315 after the
rebase. Renumber the later arrival to t/316 and extend the nightly
stage5-ges-locking range to 276-316 so the renamed test runs in nightly.

Spec: spec-5.13-clean-leave-reconfig.md
