Site not recognized in advanced setup

[geek-merlin]

How to reproduce (with today's 8.0.x-dev):

• Have a drupal 7.x multisite containing a site named "foo", publicly accessible as http://www.foo.com
  (...and some "default" site)
• $sites.php maps www.foo.com to foo
• some modules need the correct $SERVER['host'] also in drush calls, so sites/foo/drushrc.php contains uri = www.foo.com and sites/default/drushrc.php contains uri = www.default.com

Now do
drush @sites sa @self
which internally does
drush --uri=foo sa @self

Expected: uri=http://www.foo.com
Experienced: uri=default

(At least i think these are the relevant things to reproduce...)

The real-world trouple is a multisite, that caches links with wrong base_url in drush cc all.

It turns out there are 2 issues in here, see the next 2 pull requests which together fixed the issue on my production site.

@axel-rutz I experienced a similar issue and geek-merlin@d1b5108 solves it for me without any side effects but I don't actually see a PR for it.

Closing due to inactivity and the follow-up PR (which was deemed inadequate).
