Make registration fails if quiet=TRUE

[kinto-b]

I must've been asleep at the wheel when I wrote this control flow. It doesn't make any sense

makepipe/R/make_register.R

Lines 38 to 47 in a605957

	if (!quiet) {
	msg <- "`make_register()` called outside of a 'makepipe' pipeline"
	if (exists("__makepipe_register__", parent.frame())) {
	register_env <- get("__makepipe_register__", parent.frame())
	if (!is.environment(register_env)) warning(msg, call. = FALSE)
	} else {
	warning(msg, call. = FALSE)
	return(invisible(value))
	}
	}

Will be in next release
