; Silence byte compiler in erc-netsplit-JOIN

* etc/ERC-NEWS: Partially revert edit from c9f1ad2a870 "Revive option
erc-query-on-unjoined-chan-privmsg".
* lisp/erc/erc-netsplit.el (erc-netsplit-JOIN): Silence byte compiler
warning re ignored return value from `delete' when removing nicks.
Could probably suppress rather than reconstitute since the CAR of an
`erc-netsplit-list' entry originates from the trailing "reason" param
of the instigating "QUIT" command and should look something like
"irc.example.org chat.example.org", which cannot be confused for a
nickname.
* test/lisp/erc/resources/erc-scenarios-common.el: Fix wording in
Commentary.
