Fixed mass of errors on uninstall

[alfa1]

During install if it adds xf_post -> vb_thread_id column then it will likely take a long time again and crash on this. Because I have 1.3 million posts.

alfa1Yep! I think it is problem :/

Why is it needed to add this column. Do all xf posts need to have the vbulletin ID?
Only 1% will be social group posts.
