Unfortunately I'm very busy. But I check it again and it turns out that 
the fix does not resolve the problem completely. This PR just remove the 
single file from testing so currently dub does not run unit tests in the 
single file package at all. The first variant 
(https://github.com/dlang/dub/pull/2050) fixes the issue indeed. I need 
to reevaluate these PRs and close the issue. I'll do it later.
