This was already fixed, but this is a test to make sure it definitely
is.

Fixes #7953

Our module is called when an internal request results in a file-not-found
error.  At this point we kick in and try to update the virtual host to
point to the first sensible one we find.   Unfortunately we had an error
in the counting.

Given two hosts:

    /srv/blog.example.com/
    /srv/example.com/

If a request came to the first site due to a rewrite from mod_rewrite, we'd
be invoked because of the internal-404.  We'd then fixup the hostname and
then mod_rewrite would fixup the path.

however we started counting the hostname fro the first letter, such that

    /srv/blog.example.com

would never be found.  So we'd always update the hostname to /srv/example.com
and at that point mod_rewrite would correct the path and the request would
go to the wrong vhost.

Fixes #8473

Also updated maintainers and uploaders.

Until now there were two cases:

* Email address specified - the output would be mailed.
* No email specified - then the output would get cat'd

The last case would have cron then send the output by email, so
both cases were the same!  Removed the second option.

common: Added new managed? test for ConfigFile which returns true if a file was ever managed by Symbiosis
