Issue #2285: Fix detecting sites other than default when a site-local drush is installed.

[fago]

See issue #2285 for details.

Patch works, BUT only on our macOS machines, not on our linux machines. May that help find the bug?

[fago]

This is strange, because it works fine for me on ubuntu 14.04 and 16.04 machines. With which environmments did this not work?

[BR0kEN-]

It works and should work everywhere. We definitely must not change the directory because otherwise, we're going outside from the site directory. Another solution - is to restore the previous CWD back in this particular condition.

Can someone reopen this PR?

This PR helped me today to resolve the issue with multi-site setup.

This patch unfortunately doesn't fix it in my case. I applied it with composer-patches to 8.1.15.

I'm running drush st from within a multisite directory.
