[PATCH] org-id: Fix behavior when `org-id-extra-values' is a symbol

[Erik Hetzner <egh@e6h.org>]

* lisp/org-id.el (org-id-update-id-locations): When
`org-id-extra-values' is a symbol, it should be evaluated as a
variable.

In 37a5020bb, `org-id-update-id-locations' was rewritten, and the
functionality to allow the variable `org-id-extra-values' to be a
symbol that references another variable was removed.  This change
restores that functionality.
