  tests: always unlink created config files
  
  While our tests in config::include create a plethora of configuration
  files, most of them do not get removed at the end of each test. This can
  cause weird interactions with tests that are being run at a later stage
  if these later tests try to create files or directories with the same
  name as any of the created configuration files.
  
  Fix the issue by unlinking all created files at the end of these tests.
  
  (cherry picked from commit bf662f7cf8daff2357923446cf9d22f5d4b4a66b)
