; Set explicit hook depth for erc-once-with-server-event

* lisp/erc/erc.el (erc-once-with-server-event): Set hook depth to -95.
* test/lisp/erc/erc-scenarios-base-association-nick.el: Improve
comment.
* test/lisp/erc/resources/erc-d/erc-d-tests.el
(erc-d--render-entries): Remove do-nothing assertion since its purpose
was unclear and likely dubious, as was incidentally highlighted by the
addition of a function not present on older Emacsen, which this test
still needs to run on.
