OPENEUROPA-1271: Valueless options are ignored when put into configuration

Started with a test that proves that the valueless --skip-permissions-setup option is ignored when it is put in a configuration file.

Now I will commit the fix, this should turn the test green.

I had to restart this chain of commits because the composer executable was missing on the test bot, causing unrelated failures. By cleaning out the commit history and restarting it this got auto-closed by Github.

The problem with the missing composer file was still present on the first test run, but only on PHP 7.1. I think this is not a problem for reviewing this PR, since the test still ran successfully on PHP 5.6 and shows the correct error there, so it is proven that the test works correctly:

--- Expected
+++ Actual
@@ @@
-'0555'
+'0775'

/test/task-runner/tests/Commands/DrupalCommandsTest.php:64

The second commit ran successfully and proves that the bug is now fixed.
