Subject: [PATCH] Fix test_history_path_detection panic: call test_init()

test_history_path_detection calls add_pending_with_file_detection(),
which spawns a thread pool task via ThreadPool::perform(). This
requires threads::init() to have been called, otherwise
assert_is_background_thread() panics.

Add the missing test_init() call, matching other tests that use
subsystems requiring initialization.

Closes #12604
