 Used by the "My Account" menu, see [16077], the `$user_identity` global is
 back compat / 'deprecated' and we shouldn't use it, especially when we now
 have the full `$current_user` object via wp_get_current_user() anyway.

 See [3566] for "Setup global user vars.  Used by set_current_user() for
 back compat."

 Patch also makes use the local `$user_id` variable instead of re-calling
 get_current_user_id() again.
