Broken tests

This test is supposed to test that credentials are collected from mimikatz 14 and used to access mimikatz 15. It should be a depth 2 test and shouldn't include valid credentials for mimikatz 15 in the configuration.

Also check the depth_1_a test, as this has comments about mimikatz password stealing. I'm not sure how this can be properly tested with a depth 1 test.
