Bug: Refiling is broken [7.6 (release_7.6.132.gd8bd4)]

[Bernt Hansen <bernt@norang.ca>]

Hi Bastien,

Bulk refiling from the agenda (B r) no longer works for me.  Git bisect
identifies the following commit as the problem:

| 651a537e49495b283602d7ef8979d364ef8dfbf9 is the first bad commit

|     * org.el (org-refile-get-location): exclude current heading

I get the following backtrace when trying to bulk refile from the
agenda:

Refiling also seems to be similarly broken (C-c C-w)
