For myself I have deinstalled elpa-org for the moment. But this mitigation – or the suggested changing of the load-path – introducing unnecessary modifications, which will – Murphy's Law – become persistent.
A „clean solution“ should avoid duplicated distribution of the same functionality – especially if one „shadows“ the other. I suggest strongly to drop the duplicated parts from the main emacs-el and either only distribute as 'elpa' or move to distinct packages setting conflicts against the elpa version (and vice versa!) . The problem of the duplicated 'elpa-org' distribution applies also to – on my system – to 'elpa-seq' and 'elpa-let-alist'.
