Open phpunit.xml uses incorrect file

[JoakimLofgren]

Seems like the folder exclusion setting is not used, so it goes into vendor/ and grabs the first it finds... Even though app/phpunit.xml.dist is "closer" than vendor/.../phpunit.xml

I use the default plugin settings and I don't have a app/phpunit.xml file.

Thanks for the bug report. You're absolutely right - this setting isn't used.

I've just pushed a fix which should use this setting. Hopefully that will solve your problem.
