In #234 we added Behat code coverage support which works great except for a few minor issues.

Incorrect autoload require statement here:

The path is wrong.

Class mismatch

Sometimes SebastianBergmann\CodeCoverage\ProcessedCodeCoverageData is loaded but SebastianBergmann\CodeCoverage\Data\ProcessedCodeCoverageData is expected (or the other way around?). That means somehow some older versions of that class are loaded. Needs investigating.

Very slow tests

Behat tests with coverage reporting take much longer to process. In the case of entity-command the job is even cancelled after 6 hours because it's still not finished.

We should look into improving this. Maybe pcov is faster than xdebug. Or we split up the job into multiple ones to run in parallel (see #189)
