* test/lisp/erc/erc-scenarios-base-reuse-buffers.el
(erc-scenarios-common--base-reuse-buffers-channel-buffers): Extend some
timeouts.
* test/lisp/erc/erc-scenarios-keep-place-indicator.el
(erc-scenarios-keep-place-indicator--follow): Prefer `ert-skip' here
instead of an :unstable tag because ERC's tests can run locally on some
systems with "SELECTOR=t".
