  core::init tests: reverse init/shutdown We want a predictable number of initializations in our multithreaded init test, but we also want to make sure that we have _actually_ initialized `git_libgit2_init` before calling `git_thread_create` (since it now has a sanity check that `git_libgit2_init` has been called). Since `git_thread_create` is internal-only, keep this sanity check. Flip the invocation so that we `git_libgit2_init` before our thread tests and `git_libgit2_shutdown` again after.
