43fc5b0078 Make <c-n> show completion menu again when autocomplete is off
As pointed out in [1], when insert mode autocomplete is disabled,
<c-n> could be used to activate insert mode completions temporarily
[2].  This regressed in 6f7c5aed (Do not show custom completions when
autocomplete is off, 2022-01-03). Fix this by enabling completions
on <c-n>/<c-p>. This allows us to remove a special case for explicit
completers.

Alternative behavior (future?): make <c-n> toggle completion like
<c-o>.  This can be done today, as suggested by Screwtape on IRC:

	map global insert <c-n> %{<c-o><c-n><a-;>:toggle-ctrl-n<ret>}
	define-command toggle-ctrl-n %{
		hook global InsertCompletionShow .* %{ map window insert <c-n> <c-n> }
		hook global InsertCompletionHide .* %{ unmap window insert <c-n> <c-n> }
	}

[2] <c-n> completion only lives for the lifetime of the completion
    menu, whereas <c-o> lasts until you exit insert mode. This means
    that autocompletion is much more convenient than <c-n> or <c-x>f,
    because those require an explicit completion request for each
    path component.

a4953c59ce Enable test/regression/0-autocomplete-overrules-completers
test/run skips directories without the "cmd" file, so it doesn't run
this test.  Fix this by adding an empty "cmd", like elsewhere.

6f7c5aed10 Do not show custom completions when autocomplete is off
As reported in [1], completions provided by "set global completers
option=my_completion" activate insert mode autocompletion, even when
the autocomplete option does not have the insert mode flag.

This happens because InsertCompleter::on_option_changed() calls
InsertCompleter::setup_ifn(), which shows the completion pager.
Fix this by computing whether the completion pager is enabled;
otherwise we can return early from setup_ifn().
The completion pager is enabled if the autocompletion bit is set,
or if the user has requested explicit completion.
