Don't recurse in erc-server-delayed-check-reconnect

* lisp/erc/erc-backend.el (erc-server-delayed-check-reconnect): Run
`reschedule' function on a timer to avoid growing the stack when
calling `delete-process'.
* lisp/erc/erc-common.el (erc--favor-changed-reverted-modules-state):
Fix `pcase' condition so that changing an option to its standard value
does not earn a "STANDARD" label in Customize if that value differs
from the saved one.
* lisp/erc/erc.el (erc-open-socks-tls-stream): Reword doc string.
* test/lisp/erc/erc-tests.el (erc--with-dependent-type-match)
(erc--with-dependent-type-match): Remove useless tests (bug#71178).
* test/lisp/erc/resources/base/reconnect/unexpected-disconnect.eld:
Await phantom EOFs and PINGs to somewhat account for a race that can
result in a failure when running the suite in parallel with -jN.
* test/lisp/erc/resources/erc-scenarios-common.el
(erc-scenarios-common--print-trace): Set `debug-on-error' to t
so that errors in timers always trigger test failures.
