  Reset all static variables to NULL in clar's __cleanup
  
  Without this change, any failed assertion in the second (or a later) test
  inside a test suite has a chance of double deleting memory, resulting in
  a heap corruption. See #1096 for details.
  
  This leaves alone the test cases where we "just" use cl_git_sandbox_init()
  and cl_git_sandbox_cleanup(). These methods already take good care to not
  double delete a repository.
  
  Fixes #1096
