Bug proof: include and groups don't work together

[Slamdunk]

Hi, to make parallel tests work I need to split the into groups, but my tests are also split with the include directive.

It turns out the they don't work together: groups of tests of included suites seem ignored.

This PR is a bug proof, any tip on where to put hands to solve this is welcome.

The code has everything to test the bug, but for sake of completeness:
