Run AB and Unit tests in different jobs

Refs #59 and takes a small step in that direction

I think this went in the opposite direction 😅

I was hoping the Autobahn tests (client+server) could run in a single job. The end result being there would be 1 job per PHP version. Autobahn and PHPUnit should be run together because one of the PHPUnit test cases is to check the output of the Autobahn test results. AB doesn't fail to stderr if a test fails.

Haha ok, then I think I misunderstood. What you wanted with that 😂 .

Ok that makes sense, then paralyzing jobs is going to be a bit harder. But lets see if we can still utilizing something like this in a different way.
