  Fix issue #22359 - joiner over an empty forward range object liable to
segfault

  If you pass it a range of class-based ranges, the initialization to
  `typeof(_current).init` will be `null`. Calling the `save` method
  on `null` will naturally be a memory violation. This generic check
  will handle null without harming any other type since save of any
  init value will be another init value.
