; Increase ERC test server queue size

* test/lisp/erc/erc-scenarios-scrolltobottom.el
(erc-scenarios-scrolltobottom--normal,
erc-scenarios-scrolltobottom--all): Use updated name for test fixture.
* test/lisp/erc/resources/erc-d/erc-d.el
(erc-d--initialize-client): For lengthy batches, `erc-d--filter' may
run multiple times before `erc-d--on-request' can pull from the queue,
which results in discarded incoming messages and match failures.
(erc-d--m, erc-d--log): Convert to ordinary functions.
* test/lisp/erc/resources/erc-scenarios-common.el
(erc-scenarios-scrolltobottom--normal,
erc-scenarios-common-scrolltobottom--normal): Rename test fixture from
former to latter and attempt to fix intermittent failure re
`count-screen-lines'.
