pager: ensure wrapped dispatch._runcommand runs before color's

An upcoming patch will teach color to potentially act differently if the
pager is active. Since both extensions wrap the same function
(dispatch._runcommand) to change behavior, we must guarantee that
pager's wrapped function runs before color's so color may read the
breadcrumb left by pager.
