org-clock.el (org-clock-get-table-data): Bugfix

* org-clock.el (org-clock-get-table-data): When :link is `t'
in the clocktable parameters, bracket links in the clocktable
should only contain their description, other C-c C-o will try
to open the bracket link at point instead of the headline.

Thanks to Alexey Lebedeff for providing a preliminary patch for this.
